摘要
采用膨胀计法 ,在 30℃的恒温条件下 ,研究了由N 正丁基硫代吖啶酮 (NBTA)、二甲基二苯基碘钅翁盐(DMDPI)、硫代水杨酸 (TS)和甲基丙烯酸甲酯 (MMA)组成的光敏聚合体系在氙灯照射下的聚合反应动力学 ;研究了温度对光聚合反应速率的影响。结果表明 ,30℃下 ,该体系的光聚合速率与各组分的关系可用下述动力学方程式表示 :Rp=K[NBTA]0 78[DMDPI]0 56[TS]0 6[MMA]0 94 ;随着温度的增加 。
Kinetic study of photopolymerization of methyl methacrylate(MMA) was carried out at 30°C, by using dilatomer under Xeon lamp. Meanwhile, the effect of temperatures was also researched. The initiating system comprises N-(n-butyl) thioacridone (NBTA), dimethyldiphenyl-iodonium salt (DMDPI) and thiosalilylic acid(TS). The conclusion shows that the kinetic equation of polymerization is RP = K [NBTA]0.78[DMDPI]0.56[TS]0.6[MMA] 0.94, and the reaction of photopolymerization speeds up with the increasing of temperature.
