中文摘要：
从聚甲醛的制备出发，综述了引发剂、共聚单体的研究成果，进而概述了聚甲醛的结构以及性能方面的研究进展。重点强调了聚甲醛的高性能化研究，即在合成过程中通过共聚单体来引入侧基，以改善聚甲醛的韧性、热稳定性等性能。通过优化共聚单体的分子结构，调节共聚单体的含量来合成高性能化的聚甲醛树脂，以适应高速、高温、高压的工作环境。
英文摘要：
This paper reviewed research achievements of initiator and comonomer in the preparation of polyoxymethylene,and then summarized their research progress in structure and performance. It was pointed out that we must synthesize high performance polyoxymethylene such as introducing comonomers with sidegroups in order to improve toughness and thermal stability of polyoxymethylene. By optimizing molecular structure of comonomer, adjusting the amount of comonomer, we could gain high performance polyoxymethylene resin to adapt to the high speed, high temperature and high pressure working environment.
