Polymerization method utilizing a three-phase system: water-in-oil-in-water or oil-in-water-in-oil comprising the steps a) adding the monomer material to be polymerized into the innermost water or oil phase; b) adding, with mechanical agitation, the product of Step a to the middle oil or water phase, said phase containing appropriate surfactant, whereby an emulsion is formed; c) adding, with mechanical agitation, the emulsion product of Step b to the outermost water or oil phase, said phase containing appropriate surfactant, wherein polymerization proceeds in the innermost water or oil phase until complete.
利用三相系统的聚合方法:水包油或油包水的聚合方法,包括以下步骤 a) 将待聚合的单体材料加入最内层的水相或油相; b) 在机械搅拌下,将步骤 a 的产物加入中间的油相或水相,所述相含有适当的表面活性剂,从而形成乳液; c) 在机械搅拌下,将步骤 b 的乳液产物加入最外层的水相或油相,所述相含有适当的表面活性剂,聚合作用在最内层的水相或油相中进行,直至完成。
