In an effort to make the process more commercially viable, scientists at Qingdao Institute of Bioenergy and Bioprocess Technology, China, have designed and synthesized efficient catalysts for the hydrolysis of starch and cellulose based on copolymers of poly(acrylic acid) and poly(styrene sulfonic acid). The random copolymer PAA-r-PSSH gave the highest glucose yield among the prepared catalysts which the team attribute to the synergic effect of the SO3H and COOH groups in the polymer chain.
