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。
In this paper, the laser scattering method with high sensitivity and angle scanning technology was used to systematically study the cross-linking copolymerization of styrene with ethylene glycol dimethacrylate and divinylbenzene to obtain the gelation point, reaction rate, phase separation Point, correlation coefficient and mean square permittivity fluctuation on the macroscopical and submicroscopic levels, and found by comparison that there are both common laws and their own characteristics between different reaction systems. A high degree of understanding of monomer activity and formula on the polymerization reaction, deepen the understanding of the law of gelation reaction.
