Abstract

Enzymatic synthesis of a new class of cross-linkable polyesters has been achieved. Polymerization of divinyl sebacate and glycerol using Candida antarctica lipase as catalyst in the presence of unsaturated higher fatty acids produced the polyesters having an unsaturated group in the side chain. The polyester was subjected to hardening by cobalt naphthenate catalyst or thermal treatment, yielding cross-linked transparent film.

摘要

已实现了一类新型可交联聚酯的酶促合成。在不饱和高级脂肪酸存在下，以南极假丝酵母脂肪酶为催化剂，使癸二酸二乙烯酯与甘油发生聚合反应，生成了侧链带有不饱和基团的聚酯。该聚酯通过环烷酸钴催化剂或热处理进行硬化，得到交联透明薄膜。
