Abstract
The ring‐opening polymerization of adipic anhydride and the ring‐opening copolymerization of adipic anhydride with ϵ‐caprolactone catalyzed by single component rare earth trisphenolate have been reported. The structure of the copolymer poly(CL‐b‐AA) has been characterized by SEC, ^1^H NMR and DSC.

Random copolymerization of trimethylene carbonate (TMC) with e-caprolactone (CL) catalyzed by rare earth chloride-epoxide or rare earth isopropoxide has been investigated for the first time. It was found that in the presence of epoxide, rare earth chlorides have high activities for the copolymerizat
