摘要

用激光喇曼光谱作探针，实时跟踪甲基丙烯酸甲酯的预辐射聚合过程。以1642 cm,-1,和600 cm,-1,的喇曼谱带作为分析线对，得到聚合的动力学曲线，单体转化率达86%。分析表明：在甲基丙烯酸甲酯的本体自由基聚合过程中，体系物理状态的变化影响了自由基的反应活性。

Abstract

The preirradiation polymerization process off-source of methylmethacrylate (MMA) was monitored in real-time by laser Raman probe. The characterestic Raman peaks of 1642 cm,-1, and 600 cm,-1, have been used as analytical lines to obtain the polymerization kinetic curve. The conversion of monomer was up to 86%. Analysing the results showed that the change in physical state of the system has effect on the activation of free radicals.
