Effect of solvent on the lipase-catalyzed synthesis of poly(octanedioladipate-co-octanediolmalate)
Terpolymer of 1,8-octanediol, adipic acid, and L-malic acid was synthesized via a lipase-catalyzed direct polycondensation in different organic solvents. The results of GPC show that an organic solvent possessing low polarity is a better organic medium for the lipase-catalyzed polymerization. The H-1 NMR spectra of the obtained copolymer samples indicate that hydroxy groups of L-malic acid do not take part in the polymerization reaction.
