Sabine Beuermann studied chemistry and received a Ph.D. in Physical Chemistry in the group of Michael Buback at the Georg-August-University of Göttingen. After working as a visiting scientist at the DuPont Experimental Station in Wilmington/DE, she returned to Göttingen to work on her habilitation, which was finalized with the habilitation thesis on homogeneous phase polymerizations in supercritical carbon dioxide and the venia legendi for Technical and Macromolecular Chemistry. Since 2006 she is professor of Polymer Chemistry at the University of Potsdam. Current research interest include synthesis, characterization, and modification of vinylidene fluoride polymers, polymerizations in supercritical carbon dioxide or ionic liquids, reversible deactivated radical polymerizations, functionalization of nanoparticles or fullerenes with fluorinated polymers, and detailed investigations into the kinetics of radical polymerizations. Since 1996 she is a member of the IUPAC Subcommittee on “Modeling of Kinetics and Processes of Polymerization”.

What was the motivation behind the research in your recent Polymer Chemistry paper? (DOI: 10.1039/C1PY00427A)

Initially, we started to look into vinylidene fluoride polymerizations, because I was interested in the kinetics and to use supercritical carbon dioxide as an environmentally friendly reaction medium. Since the very first PhD student working on this topic, M. Imran-ul-haq, had a background in organic chemistry he also started with the functionalization to an azide. Because of its ferro-, piezo, and pyroelectric properties there are many advanced applications for PVDF. Of particular interest are systems with separated PVDF domains, e.g. voids in PVDF or layer formation due to self-aggregation. From this point it was pretty obvious to think about the synthesis of block copolymers with PVDF. However, with the exception of iodine transfer polymerizations vinylidene fluoride is not well suited for reversible deactivated radical polymerization and thus, there were almost no reports on PVDF block copolymers. Obviously, using polystyrene as a second block was only the starting block. We are now working on block copolymers with a number of other polymers.

Why did you choose Polymer Chemistry to publish your work?

Although being a young journal Polymer Chemistry is already well-recognized and the fraction of articles I am interested in is comparably large. Moreover, I like the design of the articles, and the “clean” structure of the homepage. After publication of the article I can also add that the whole process was very fast and went very smoothly.

In which upcoming conferences may our readers meet you?

I am most excited on attending the 20th International Symposium on Fluorine Chemistry in Kobe in July, because it will be my first trip to Japan. In addition, I will go to the Freiburger Makromolekulares Kolloquium in February, the Polymer Reaction Engineering conference in May and probably to MACRO2012 in June.

How do you spend your spare times?

In my spare time I try to make as little plans in advance as possible. I enjoy walking in the beautiful parks and surroundings of Potsdam, trips to the North or Baltic Sea and visiting family.

Which profession would you choose if you were not a scientist?

Maybe a historian, but I am very happy with the choice I made.

Graeme Moad was born in Orange, NSW, Australia. He obtained his BSc (Hons, First Class) and PhD from the University of Adelaide in the field of organic free radical chemistry. After undertaking post-doctoral research at Pennsylvania State University in the field of biological organic chemistry he joined CSIRO in 1979 where he is is currently a chief research scientist.  He is also a project leader within the Cooperative Research Centre for Polymers. Dr Moad is author or co-author of over 150 publications, co-inventor of 34 patent families (12 relate to the RAFT process) and co-author of the book “The Chemistry of Radical Polymerization”. More than 12,500 papers cite his work and his h-index is 52. His research interests lie in the fields of polymer design and synthesis (radical polymerization, reactive extrusion, polymer nanocomposites) and polymerization kinetics and mechanism. Dr Moad is a Fellow of the Royal Australian Chemical Institute and he has recently been elected as a titular member of the Polymer Division of the International Union of Pure and Applied Chemistry.

What was your inspiration in becoming a chemist?

No specific inspiration. I sort of drifted into science and chemistry through a process of natural selection.

What was the motivation behind the research in your recent Polymer Chemistry paper? (DOI: 10.1039/c2py00529h)

The motivation for this particular line of research was provided by my colleague John Tsanaktsidis and post doc Shadi Houshyar who, having heard us talk on the precision of RAFT polymerization, had the perhaps naïve idea that the process might be used to construct polymer chains precisely.  While aware of their endeavour, I only became directly involved after they showed that it didn’t work.

Why did you choose Polymer Chemistry to publish your work?

The decision to send this paper to Polymer Chemistry was a direct consequence of the arrival of an invitation from Professors Christopher Barner-Kowollik, Jean-François Lutz, and Sebastien Perrier to contribute to the Themed Issue on New Methods of Polymer Synthesis planned for 2012. This fortuitously occurred at the time that we were contemplated publication of the work. Of course we were three months behind the deadline with our submission. The emerging reputation of Polymer Chemistry as one of the premier journals in the field was also important in our choice.

In which upcoming conferences may our readers meet you?

I will be at the upcoming 33^rd Australian Polymer Symposium, 12-15 February in Hobart, Tasmania.  Later in the year I will also present at IUPAC Macro 2012, June 24-29 in Blacksburg, Virginia, USA and at Warwick 2012, July 9-12 in Warwick, UK.

How do you spend your spare times?

Spare times?  Much is taken up by our two children. Another large portion by that chemistry that does not directly align with current work, writing papers… In what little remains: bushwalking, reading, maintaining a genealogical web site.

Which profession would you choose if you were not a scientist?

I suspect no matter what profession I chose I would still be a scientist. My mother thought I should go into banking. An aptitude test taken in final year of high school indicated I should be an architect (in a chemistry way, maybe I took that suggestion on board).  But having obtained a borderline marks in English, and grades in Maths, Chemistry and Physics sufficient to gain a University Scholarship (in the only year in which a good grade in English was not a prerequisite), my path was set.

I did rebuild a house once (in my spare time, pre-kids), that was enjoyable.

Directeur de Recherches at CNRS, Bruno Ameduri leads the “Fluoropolymers and Energy” team at the “Engineering and Macromolecular Architectures” Team of Institute Charles Gerhardt in Montpellier, France. His main interests focus on the synthesis and the characterization of fluorinated monomers (including cure site monomers and telechelics), telomers and copolymers for various applications such as surfactants, elastomers, coatings, and polymers related to energy (fuel cell membranes, polymer gel electrolytes for Li-ions batteries and PV). Coauthor of one book, 22 reviews or chapters of books, more than 210 peer review publications and coinventor of more than 55 patents, he is also a member of the American and French Chemical Societies and is a member of the Editorial Boards of the Journal of Fluorine Chemistry, European Polymer Journal, Polymer Bulletin, and Associated editor of Polymer Journal (Japan). Out of research, Bruno enjoys cycling, skiing, jogging and playing soccer and tennis with his 2 sons,  and is an active member of the “Rire” Association and, dressed as a clown, visits sick children in hospitals of Montpellier and abroad.

What was your inspiration in becoming a chemist?

I had good teachers at the secondary school who showed their motivation and interested me and other pupils. Fortunately, we had pratcial works (every friday morning I remember!) and this was quite funny.
I was also fortunate to get execllent Professors at the University and abroad when I had the chance to go to Canada…last centuary!

What was the motivation behind the research in your recent Polymer Chemistry paper? (DOI: 10.1039/C1PY00394A?

Regretably, people, mammals, fish and birds have fluorine (especially fluorinated surfactants such as PFOA and PFOS)  in their blood and these “PCBs of the XXIst centuary” are spread all other the Earth. There was a emergency to find out new products that should be able to decompose and so far I cannot guaranty that those sugegsted in this article can be metabolized or decomposed through humun systems.

Why did you choose Polymer Chemistry to publish your work?

First, I was quite angry against several journals who rejeceted right away the draft…even after explaining to the Editor that he (she) had fluorine in his (her) blood. Then, I promised to Dave Haddleton to submit a MS in that nice journal….and you know the story.

In which upcoming conferences may our readers meet you?

Mostly in Fluorine Chemistry conferences (India-Feb. 2012), in Valencia , Spain, for the Valencia Fluorine days (May 2012); Kyoto for the Intenational Conference in Fluorine Chemistry, (July 2012) and Fluoropolymers (Oct. 2012).

How do you spend your spare times?

Biking and playing football with my sons (but they are now too fast for me-they train me nicely!) or colleagues from the Lab (big competition between permament and non-permanent researchers!!)…and volunteer as cliniclown in children Hospitals (Montpellier, USA, and Japan). This “once a month activity” is an excellent release of stress, source of humbleness, and shows me other realities of our world…

Which profession would you choose if you were not a scientist?

Hard to say…something involving both sport and kids could fit well…
