Title:
ポリアセタール共重合体およびその重合方法
Document Type and Number:
Japanese Patent JP7061479
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide a polyacetal copolymer and a polymerization method having excellent production stability and heat stability such as the amount of formaldehyde generated while maintaining the level of rigidity, creep property, and sliding property. This goal was attained by a polyacetal copolymer obtained by copolymerizing a trioxane, a cyclic acetal compound having a C2 or higher oxyalkylene group in the ring, and a polyepoxy compound having two or more epoxy groups per molecule and, other than the epoxy groups, comprising a hydrocarbon, and a method for polymerizing a polyacetal copolymer that copolymerizes a trioxane, a cyclic acetal compound having a C2 or higher oxyalkylene group in the ring, and a polyepoxy compound having two or more epoxy groups per molecule and, other than the epoxy groups, comprising a hydrocarbon, in the presence of a cationic polymerization catalyst.
