摘要

由乳化剂聚乙二醇壬基苯基醚ＯＰ、聚乙二醇壬基苯基醚（ＴＸ—４）、丙烯酸胺、水和煤油组成微乳液时，体系中水相丙烯酸胶浓度及体系温度对乳化剂最小量有明显的影响；而ＯＰ、ＴＸ—４比例及油水比例的影响不大．本文研究了辐射引发微乳液聚合的动力学，得到如下表达式：聚合速率及聚合物特性粘数的表观活化能分别为５３．２ＫＪ／ｍｏｌ，－３３．２ＫＪ／ｍｏｌ．聚丙烯酸胺微乳液具有特殊的增稠性能，与聚电解质增稠剂相比，电解质对增稠效果的影响不大，而其他表面活性剂的影响较大．

Abstract

n the microemulsion composed of OP (nonyl phenyl polyoxyethylene

HLB= 13.2). TX- 4 (nonyl phenyl polyoxyethylene

HLB= 8.0)

H2O and kerosene

the minimum amount of emulsifier required to produce microemulsion were studied. It was found that there are obvious grafting effect of emulsifier in the process of radiation induce polymerization. The kinetics of radiahon induced microemulsion polymerization were studied with dilatometer and the intrinsic viscosity of the resulted polymer were determined with Ubbelode capillary viscometer. The results were as: In comparison with polyelectrolyte

the latex resulted from microemulsion polymerization is a special thickener with a good electrolyte resistibility and apoor surfactant resistibility.
