Scientists at Southern Methodist University, USA, have shown that retaining the active end group functionality during grafting-from RAFT polymerizations from model proteins can give thermoresponsive diblock copolymer–protein conjugates. The team behind the research claim that the reduced steric limitations of this method could help create a wide variety of block copolymer bioconjugates with high molecular weight synthetic components.
