摘要：
The polymerization of acrylonitrile （AN） initiated by polypropylene based-polyamidoxime （PPAO）-thiourea （TU） system was investigated at [TU]/[PPAO]>0.5 molar ratio. It shows that the variation of the concentrations of PPAO, thiourea and nitric acid does not exert an observable influence on the reaction rate. The overall rate of polymerization （R;） isR;= 2.07e;[ AN];The zero order dependence on PPAO and thiourea concentrations and the lowest value of the collision frequence factor were considered to be a feature of the primary radical termination.
