SYNTHESIS OF BLOCK COPOLYMERS OF STYRENE AND N-(p-SUBSTITUTED PHENYL) MALEIMIDES BY ANIONIC POLYMERIZATION
摘要:
The block copolymers were synthesized by anionic polymerization 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 copolymers had been formed.From the results of thermogravimetric analysis,it could be concluded that the block copolymer had a much better thermal stability than random copolymers prepared by radical polymerization.Also the surface hydrophilicities of the two kinds of copolymers were compared.
