## Abstract Poly(L‐lactide)‐poly(ethylene glycol) multiblock copolymers with predetermined block lengths were synthesized by polycondensation of PLA diols and PEG diacids. The reaction was carried out under mild conditions, using dicyclohexylcarbodiimide as the coupling agent and dimethylaminopyrid
## Abstract Two series of triblock copolymers of poly(ethylene glycol) (PEG, number‐average molecular weight __M__~n~ = 6000) and poly(L‐lactide) (PLLA) or poly(D‐lactide) (PDLA) were prepared by ring‐opening polymerization of lactide initiated by PEG end groups using stannous octoate as a catalyst
## Abstract Novel thermoreversible gelation behavior of aqueous solutions of ABA‐type triblock copolymers composed of the central polyethylene oxide (PEG) block and two poly(D,L‐lactic acid‐__co__‐glycolic acid) side blocks was found. Phase transition characteristics, such as critical gel concentra
