Abstract

Aliphatic polyesters containing thioester linkages were enzymatically prepared by both the copolymerization of lactone with mercaptoalkanoic acid and by the transesterification of polyesters with mercaptoalkanoic acids. The enzymatic copolymerization of ε‐caprolactone with 11‐mercaptoundecanoic acid (11MU) and 3‐mercaptopropionic acid (3MP) was performed under reduced pressure using an immobilized lipase from Candida antarctica (CA). The transesterification of poly(ε‐caprolactone) and poly[(R)‐3‐hydroxybutyrate] was carried out with 11MU and 3MP using lipase CA under reduced pressure.

## Abstract A series of random sulfonated copolyimides containing aliphatic linkages (co‐SPIAs) with controlled degrees of sulfonic acid groups were synthesized via a conventional two‐step polyimidization method. 2,4‐Diaminobenzene sulfonic acid (2,4‐DABS) and 1,6‐diaminohexane (DAH) were used as s

## Abstract **Summary:** Aliphatic dithiol‐diacid type polythioesters were first enzymatically prepared by the direct polycondensation of hexane‐1,6‐dithiol and diacid diesters using the immobilized lipase from __Candida antarctica__ (lipase CA). As a typical example, diethyl sebacate and hexane‐1,
