摘要
综述了聚甲醛(POM)的增韧、耐磨改性及改善POM热稳定性、耐候性、阻燃性能的研究成果,介绍了POM用作PTC导电材料的现状。指出应加强POM合成过程的高性能化研究,在POM合成过程中通过共聚单体引进多功能基团,为进一步地改性提供条件;调节共聚单体数量、优化分子结构的设计,合成系列化、功能化和高性能化POM;开发多功能普适性增容剂及反应性增容剂是物理改性的关键;原位聚合及橡胶微交联在复合体系内可形成互穿网络是有效增容的一种新途径。
Current research status were summarized on toughened, wear-resistant and self-lubricated, thermal Stability, flame retardancy of polyoxymethylene（POM） and its application in PTC condcting material. It was pointed out that we must think much of the synthesize of high performance POM for further modification such as introducing copolymer monomer with muhifunctional groups in processing. By adjusting the number of copolymer monomer, optmizing molecule structure, we could gained seriational, functional and high performance POM. The key of physical modification was muhifunction and reactive comptibilizer. It was a good way that POM was modified by in-situ polymerization and in-situ crosslinked rubber.
