An optically active rod-coil-rod tfibloek eopolymer containing poly(ethylene oxide)(PEO) as the flexible segment and poly {(+)-2
5-bis[4’-((s)-2-methyl butoxy) phenyl] styrene} (PMBPS) as the rigid segment
PMBPS-b-PEO-b-PMBPS.was synthesized via atom-transfer radical polymerization.The PMBPS block had a stable helical conformation with an excess of screw sense in solution.The self-assembly behavior of the tnblock copolymer in dioxane/water mixed solvents was examined by means of TEM and turbidity measurements.The tfiblock copolymer molecules aggregated when water content in the system was about 2wt% The higher the initial polymer concentrations
the lower the critical water content.They formed vesicles with highly dispersed outside diameters
but they had a relatively uniform wall thickness of (27±3) nm.
