摘要

在水分散的细乳液体系中,以S-正十二烷基-S′-(α,α′-二甲基-α″-乙酸基)三硫代碳酸酯为链转移剂、偶氮二氰基戊酸为引发剂,采用连续加料的方式,依次引发异戊二烯、苯乙烯和甲基丙烯酸甲酯等单体聚合,制备了结构明确的聚异戊二烯-b-聚苯乙烯-b-聚甲基丙烯酸甲酯三嵌段共聚物。采用凝胶渗透色谱、核磁氢谱和差示量热等方法对嵌段聚合物进行了表征。

Abstract

In aqueous dispersion/microemulsion system,with S-1-dodecyl-S′-(α,α′-dimethyl-α″-aceticacid) trithiocarbonate as chain transfer agent,4,4′-azobis(4-cyanopentanoic acid) as the initiator,triblock copolymer polyisoprene-b-polystyrene-b-poly(methyl methacrylate) was synthesized by RAFT-microemulsion polymerization.Where monomers such as,isoprene,styrene and methyl methacrylate were added and initiated successively.The structure of PIP-b-PS-b-PMMA was confirmed by GPC,¹H-NMR and DSC.
