%X Novel triblock copolymers of poly (L-lactide)-poly
(ethylene glycol)-sebacate-poly (ethylene glycol)-poly (L-lactide) were
synthesized by Ring-Opening Polymerization of different ratios of L-lactide with
other three pre-prepared poly (ethylene glycol)-sebacate-poly (ethylene glycol)
polymers, coded A, B and C which had different poly (ethyleneglycol) chain
lengths. The copolymers were characterized by FTIR and <sup><span style=\"font-family:Verdana;\">1</span></sup><span style=\"font-family:Verdana;\">H NMR
spectroscopy, which indicated that the reaction of ROP took place and led to
producing nine triblock copolymers having new different lactide chain lengths
