## Abstract Highโmolecularโweight polythiocaprolactone (PTCL) was prepared in a green process via lipaseโcatalyzed ROP of a cyclic 6โmercaptohexanoic acid (6MH) oligomer. PTCL was readily depolymerized by lipase to cyclic 6MH in dilute toluene solution, which was then readily repolymerized by the s
## Abstract **Summary:** Novel enzymatically recyclable poly(carbonateโurethane) consisting of a diurethane moiety as a hard segment and a carbonate linkage as an enzymatically cleavable unit was prepared by the polycondensation of biodegradable diurethanediol and diethyl carbonate using lipase. Th
