摘要
研究了三氧六环（TXN）与二氧七环（DXP）的阳离子开环共聚反应，并对由此制得的共聚甲醛的力学性能、热稳定性、结晶性能进行了测试．结果表明：用二氧七环制备的共聚甲醛动态热性能和力学性能优于用二氧成环制备的共聚甲醛．
The cation open-ring copolymerization of 1, 3, 5-trioxane and 1, 3-dioxepane has been investigated.The mechanical,thermal and crystal properties of the polyoxymethylene synthesized are inspected. It is found that the polyoxymethylene (POM) from 1,3-dioxepane has better properties than POM from 1,3-dioxolane.
