用甲苯为溶剂 ,采用膨胀计法对 N-苯基马来酰亚胺与苯乙烯的沉淀共聚动力学作了系统的研究 ,聚合速率方程为 RP=k[I]0 .62 [M]。同时还测定了四种 N-对位取代苯基马来酰亚胺与苯乙烯在甲苯中的共聚表观活化能 ,并由此证明四种单体与苯乙烯的聚合活性顺序及 CTC络合物的存在。
The kinetics of precipitation copolymerization of N-phenylmaleimide and styrene was studied systematically with toluene as a solvent by the dilatometer. The polymerization rate equation was RP = k [I] 0.62 [M]. At the same time, the apparent copolymerization activation energies of four N-para-substituted phenylmaleimides and styrene in toluene were also determined, and the polymerization order of the four monomers and styrene and CTC complexing The existence of things.
