pend strongly on the copolymer composition, with higher The cloud points of aqueous solutions of eight ethylene oxide values for those containing a larger percentage of EO units. (EO)/propylene oxide (PO) triblock copolymers were measured Typically, copolymers with more than 70% EO present cloud in
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
## Abstract A new route of synthesis of block copolymers was investigated. It involves the polymerization of a sideโchain liquidโcrystalline acrylate and poly(propylene glycol), modified by an esterification reaction with mercaptoacetic acid used as macrotransfer agent, in the presence of 2,2โฒโazoi
