Immobilized Candida antarctica lipase B (CALB) was successfully employed as a catalyst to synthesize silicone aromatic polyesters by the transesterification of dimethyl terephthalate with alpha,omega-bis(hydroxyalkyl)-terminated poly(dimethylsiloxane) in toluene under mild reaction conditions.

Enzymatically catalyzed polycondensation of p-xylylenediamine and diethyl sebacate resulted in oligo(p-xylylene sebacamide) with high melting temperatures (223-230 °C) and the enzymatic polycondensation of dimethyl terephthalate and 1,8-diaminooctane leads to oligo(octamethylene terephthalamide) with two melting temperatures at 186 and 218 °C.
