## 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
The adsorption of diblock and triblock copolymers of styrene and ethylene oxide, P(S-b-EO), from dilute solution is studied by ellipsometry. The copolymers consist of short poly(ethylene oxide) blocks which adsorb onto a silicon wafer and longer polystyrene blocks which do not adsorb on the substra
Two enantiomeric triblock ABA copolymers composed of poly(L-lactide)poly(ethylene glycol)-poly(L-lactide) (PLLA-PEG-PLLA) and poly(D-lactide)-poly(ethylene glycol)-poly(D-lactide) (PDLA-PEG-PDLA) were synthesized with two different middle-block PEG chain lengths by ring-opening polymerization of L-l
