SYNTHESIS OF POLYBUTADIENE-b-POLY[2-(DIMETHYLAMINO)ETHYL METHACRYLATE]AMPHIPHILIC BLOCK COPOLYMER BY MECHANISM TRANSFORMATION
机理转移法合成聚丁二烯-b-聚(甲基丙烯酸N，N-二甲氨基乙酯)两亲性嵌段共聚物

A amphiphilic block copolymer of polybutadiene((PB)-b-poly2-(dimethylamino))ethyl methacrylate](PDMAEMA) was synthesized by transformation of living anionic polymerization into atom transfer radical polymerization(ATRP).The macroinitiator,PB containing the 2-bromoisobutyryl end group(PB-Br) was attempted by anionic polymerization of butadiene with butyllithium initiator,then the living PB was chain extended with propylene oxide(PO) and terminated by 2-bromoisobutyryl bromide(BriBBr).By using PB-Br with con...
