| dc.description.abstractEn | A series of di- and triblock copolymers [poly(L-lactide-b-epsilon-caprolactone), poly(D, L-lactide-b-epsilon-caprolactone), poly (epsilon-caprolactone-b-L-lactide), and poly(epsilon-caprolactone-b-L-lactide-b-epsilon-caprolactone)] have been synthesized successfully by sequential ring-opening polymerization of epsilon-caprolactone (epsilon-CL) and lactide (LA) either by initiating PCL block growth with living PLA chain end or vice versa using titanium complexes supported by aminodiol ligands as initiators. Poly(trimethylene carbonate-b-epsilon-caprolactone) was also prepared. A series of random copolymers with different comonomer composition were also synthesized in solution and bulk of epsilon-CL and D, L-lactide. The chemical composition and microstructure of the copolymers suggest a random distribution with short average sequence length of both the LA and epsilon-CL. Transesterification reactions played a key role in the redistribution of monomer sequence and the chain microstructures. Differential scanning calorimetry analysis of the copolymer also evidenced the random structure of the copolymer with a unique T-g. | |
