英文摘要	Amphiphilic diblock copolymers containing glycopolymer segments, polystyrene block poly[2 ( β D glucopyranosyloxy)ethylacrylate](PS b PGEA), were synthesized by atom transfer radical polymerization. The morphologies of the crew cut aggregates of PS b PGEA in water were studied by TEM. I...; Amphiphilic diblock copolymers containing glycopolymer segments, polystyrene-block-poly [2-(beta-D-glucopyranosylaxy)ethylacrylate] (PS-b-PGEA), were synthesized by atom transfer radical polymerization, The morphologies of the crew-cut aggregates of PS-b-PGEA in water were studied by TEM, It has been found that for one specific diblock copolymer, the morphological transformation from spheres to vesicles was controllable by changing solvents. Spheres, rods and vesicles were found to be the dominant morphologies for PS55-b-PGEA(9) when the solvents were DMF, DMF/1, 4-doxane and 1, 4-dioxane respectively. When same solvent, e. g. 1,4-dioxane, was used, sphere to vesicle transition of crew-cut aggregates was also obtainable by using diblock copolymers of different compositions. The copolymers with a higher hydrophilic segment content tend to form spheres, while those with a lower content yield predominated vesicles.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000083723600041&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); EI; 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 3; 11; 1820-1822; 20
