Phase behavior of aqueous systems containing block copolymers of poly(ethylene oxide (PEO) and poly(propylene oxide) (PPO) was evaluated by building up temperature-concentration phase diagrams. We have studied bifunctional triblock copolymers (HO-PEO-PPO-PEO-OH) and monofunctional diblock copolymers
Block copolymers of polysulfone-poly(alky1ene oxide)-poly(dimethylsi1oxane) have been prepared by the addition of preformed a,w-bis(hydrogensily1) poly(dimethylsi1oxane) oligomers to allyl end-capped poly(alky1ene oxide)-polysulfone. The hydrosilylation reaction, catalyzed by platinum, was employed
