摘要: 本文应用具有灵敏度高及角度扫描技术的激光散射方法比较系统地研究了苯乙烯与双甲基丙烯酸乙二醇酯及二乙烯苯的交联共聚反应,得到凝胶化点、反应速率、相分离点、相关系数及均方介电常数波动等在宏观及亚微观水平上表征反应特性的参数,并通过比较发现不同反应体系间既有共同规律又有各自特性·经实验及对比可方便地从量的高度认识单体活性及配方对聚合反应的影响,加深了对凝胶化反应规律的认识。

Abstract: According to the method presented in the previous paper, the most prominent features of the method are its high sensitivity and making use of the scanning technique, the network copolymerization of styrenc with cthylene glycol dimcthacry-late and divinyibenzene were studied here by means of laser light scattering. Several parameters characterizing the properties of network copolymerization, the speed and point of gelation, the point of phase separation, the correlation coefficient α ard the mean squared average dielectric constant fluctuation62, were obtained. And some comparisons among the three systems were studied. Based on the experiments and the comparisons, this method makes possible to understand the properties of network copolymerization and ihc activity of monomers at quantitative level conveniently. Therefore, the law of the kind of chemical reactions could be understood letter.
