Fully Biobased Unsaturated Aliphatic Polyesters from Renewable Resources: Enzymatic Synthesis, Characterization, and Properties
Fully biobased saturated and unsaturated aliphatic polyesters and oligoesters are successfully prepared by Candida antarctica lipase B (CALB)‐catalyzed polycondensations of succinate, itaconate, and 1,4‐butanediol. The effects of monomer substrates and polymerization methods on enzymatic polycondens...

Fully biobased saturated and unsaturated aliphatic polyesters and oligoesters are successfully prepared by Candida antarctica lipase B (CALB)‐catalyzed polycondensations of succinate, itaconate, and 1,4‐butanediol.
