摘要

以山梨醇酐单月桂酸醋（Ｓｐａｎ２０）和聚氧乙烯山梨醇酐单硬醋酸酯（Ｔｗｅｅｎ６０）的混合物为乳化剂制备丙烯酰胺微乳液，研究了体系中Ｔｗｅｅｎ６０浓度、水相丙烯酰胺浓度对微乳液电导行为的影响．用过硫酸钾引发微乳液聚合，发现聚合开始后，体系电导率迅速下降，在聚合进入恒速期后电导不再降低．聚合的动力学表达式为：Ｒｐ∝［ＡＭ］１．１７［Ｅ］－１．２６［Ｉ］０．５；Ｍｖ∝［ＡＭ］１．０５［Ｅ］－０．９４［Ｉ］－０．６２．它与常规乳液聚合的动力学相差较大，却类似于悬浮聚合．

Abstract

he acrylamide microemulsion at appropriate Span 20

Tween 60 and acrylamide concentration were biscontinuous ones demonstrated by the study on the microemulsion conductance. It was proved by conductance change during polymerization that the transistion from the biscontinous microemulsion to W/O one starts at the begining of polymerization and stops at the begining of constant polymerization period.
