英文摘要	An optically active rod coil rod triblock copolymer 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...; An optically active rod-coll-rod triblock copolymer 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 PMRPS block had a stable helical conformation with an excess of screw sense in solution. The self-assembly behavior of the triblock copolymer in dioxane/water mixed solvents was examined by means of TEM and turbidity measurements. The triblock 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.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000228686200031&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 6; 02; 305-308
