RÉSUMÉ

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.
