成核剂对聚甲醛冲击性能影响的研究

摘要

This research studies the modification methods by adding nucleator, to promote the crystallization process of POM molding,improve the crystallization of material structure,control the size of spherulite,so as to a-chieve the purpose of improving the impact strength of POM.%本项研究采用添加成核剂改性方法，促进聚甲醛成型中的结晶过程，改进材料的结晶结构，控制球晶大小，从而达到改进聚甲醛冲击强度的目的。
