摘要: 采用同步-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/PB-MA/EP)三组分IPNs.先用同步法合成CSM/EP二组分IPNs作为骨架网络,再将PBMA溶胀进入骨架网络中.得到三组分IPNs.网络间经两次相互缠结贯穿后,比单独用同步法或分步法合成的IPNs对网络间束缚作用大,且骨架网络与PBMA组成比较接近时,相容性较好.TEM结果表明:用分步染色方法可以观察三相间的形态变化和相区尺寸的相对大小.

Abstract: Three-component 1PNs from chlorosulfonated polyethylene/polybutyl methacrylate/e-poxy resins (CSM/PBMA/EP) were synthesized by combination of simultaneous synthesis with stepwise synthesis.The compatibility depends on the component ratio in the IPNs.When the component ratio of CSM:PBMA:EP is 1:2:1,interpenetrating entanglement extent between networks is larger and compatibility is better.The morphology of three-component IPNs from CSM/PBMA/EP was investigated by using stepwise staining method.The change of phase domain size and extent of phase separation of IPNs synthesized can be observed by different staining methods.

Key words: Chlorosulfonated polyethylene, Polybutyl methacrylate, Epoxy resins, Three-component interpenetrating polymer networks
