该文提出一个改进的渗流模型 ,能把自由基交联共聚反应的主要特征包括进去 ,更真实地模拟化学凝胶化过程 ,特别是凝胶化点附近表现出来的临界行为。从模拟 St- DVB体系凝胶化过程所得的临界指数与急冷法测得的实验值基本一致
This paper presents an improved seepage model that incorporates the main features of the free radical cross-linking copolymerization and more realistically simulates the chemical gelation process, particularly the critical behavior shown near the gel point. The critical values obtained from the gelation of the simulated St-DVB system are basically consistent with the experimental values obtained from the quench method
