Poly( 1-caprolactone) -poly(ethylene glycol) -poly( 1-caprolactone) triblock copolymers (PECL) covering a wide range of poly(ethylene glycol) (PEG) lengths were synthesized with alkali metal alkoxide derivatives of poly(ethylene glycol). The effects of various factors, such as amount of the initiato

ABA-type block copolymers of poly(trimethylene carbonate) with poly(ethylene glycol) ( M n 6820), PTMC-b-PEG-b-PTMC, were synthesized by the ring-opening polymerization of 1,3-dioxan-2-one (trimethylene carbonate) in the presence of poly-(ethylene glycol) with stannous octoate catalyst, and the copo
## Abstract A series of poly(Ο΅βcaprolactone)β__b__βpoly(ethylene glycol) (PCLβ__b__βPEG) block copolymers with different molecular weights were synthesized with a salicylaldimineβaluminum complex in the presence of monomethoxy poly(ethylene glycol). The block copolymers were characterized by ^1^H N
