Novozyme 435

Enzymatic polycondensation of benzyl-2,2-bis(methylol) propionate and sebacic acid has been performed using lipase Novozyme-435 as the catalyst, subsequently enzymatic ring-opening polymerization was reacted by adding ε-caprolactone as the monomer in the same system. Then atom transfer radical polymerization (ATRP) from the macroinitiator combining α-bromoester of styrene was catalyzed by CuCl/2,2’-Dipyridyl to obtain the block copolymer successfully. The polymers obtained in different conditions were analyzed by 1HNMR and GPC.
