The production process characteristics of homopolymerization and copolymerization of polyformaldehyde(POM) were introduced, the preparation processes of formaldehyde and trioxymethylene,and the process characteristics of polymerization and post-processing in the production of copolyoxymethylene were mainly introduced. The operation status and current situation of the domestic POM production corporations were summarized. The difficulties and challenges faced by China's POM production enterprises were analyzed. It is put forward that POM industry in China should be optimized and upgraded, the technical bottleneck in the POM production should be solved in order to produce high quality POM products, the research and development of the modified POM products should be strengthened in order to produce the high-end POM modified products.
