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

Characteristics and mechanisms of the ring opening-polymerizations of 1caprolactone (CL) and trimethylene carbonate (TMC) with rare earth halides have been compared for the first time. It has been found that rare earth halides show high catalytic activities for the polymerization of TMC, but very lo
Highly random copolymers of c-caprolactone (CL) and D,L-lactide (LA) were synthesized by a new catalyst system, rare earth chloride-propylene oxide (PO) system. In the presence of propylene oxide, all rare earth chlorides tested are highly effective for the copolymerization. The influences of reacti
