摘      要：The block copolymers were synthesized by anionic pohymerization via two steps reaction. First, styrene was initiated by n-butyl lithium, then maleimides were added into the living styrene system to obtain block copolymers. 1H-NMR and FT-IR measurements indicated that block coplymers bad been formed From the esults of thermogravimetric, it could be concluded that the block copolymer had a much better thermal stability than random copolymers predared by radical polymerization. Also the surface hydrophilicities of the two kinds of copolymers were compared.
