研究了含引入氢键的PBA和PS(OH)组成的IPN体系,PS(OH)为含羟基的改性聚苯乙烯.与相应的非交联聚合物的共混体系不同,IPN均显示两相结构,一相几乎为纯PBA,另一相则是混合相;仅当PS(OH)中羟基含量高达30 mol％且其为IPN的主要成分时,才有相当量的PS(OH)溶入PBA为主的相.IPN的模量-组成行为可用Budiansky方程描述,表明两相的连续性,这一结论与透射电子显微镜的观察一致.
The IPN system composed of PBA and PS (OH) which introduced hydrogen bond was studied, PS (OH) was modified polystyrene containing hydroxyl groups.Compared with the blends of corresponding non-crosslinked polymers, IPN showed two Phase structure, one phase is almost pure PBA and the other phase is a mixed phase. Only when the hydroxyl content in PS (OH) is as high as 30 mol% and it is the main component of IPN, only a considerable amount of PS (OH) Into the PBA dominated phase.IPN modulus - composition behavior Budiansky equation can be described, indicating the continuity of the two phases, a conclusion consistent with the observations of transmission electron microscopy.
