；由阿伦尼乌斯公式求出聚合速度的表观活化能E

=20.9kJ/mol。聚合反应的转化率-时间曲线的形状受乳化时搅拌速度的影响。光学显微镜观测表明单体乳液和聚合物乳胶粒子大小无明显差别。基于以上结果，提出了单体液滴成核的机理。

Abstract

The kinetics of

Co-Gamma rays initiated inverse emulsion polymerization of acrylamide solution in kerosene with SPAN 80 as emulsifier has been studied dilatometrically. The following expressions have been determined for the conditions investigated: R

. The overall activation energy for the rate of polymerization is 20.9 kJ/mol.

The shapes of the conversion-time curves are effected by the stirring rate of emulsification. The diameters of most of the particles of monomer emulsions and polymer latexes are estimated to be about 2 micrometers by optical microscope.

Based on the foregoing results

a monomer-droplet-nucleation mechanism is proposed for the systems studied.
