摘要
本文用同步-分步结合的方法合成了氯磺化聚乙烯/聚甲基丙烯酸丁酯/环氧树脂(CSM/PBMA/EP)三组分IPN,对其形态及性能进行了研究。结果表明:随组成比的改变可以得到相容性不同的IPN,当CSM/PBMA/EP=40/40/20时,在动态力学谱上出现一个加宽的T_g转变峰;EP含量为9％时,得到相容性比较好的IPN。用分步染色的方法不仅可以观察三组分IPN的相区尺寸变化,也可以了解三相的相容程度。
The three-component IPNs from chlorosulfonated polyethylene/polybutyl methacrylate/epoxy resin (CSM/PBMA/EP) were synthesized by combining simultanous synthesis method with sequential synthesis method. It was found that varying component ratios causes diffrence of compartibility in the IPNs. When CSM/PBMA/EP=40/40/20, a winden T_(?) transition peak appears. Decreasing EP to 9％, a compatible IPN component is obtained. Using stepwise staining method to investigate the morphology of three component IPNs from CSM/PBMA/EP, we can observe the chang of phase domain size and the extent of phase seperation of IPNs synthesized by different synthetic methods.
