POLYACETAL COPOLYMER AND METHOD FOR PRODUCING THE SAME

摘要

A polyacetal copolymer which is obtained by a method which comprises copolymerizing (a) 100 parts by weight of trioxan, (b) 0.05 to 20 parts by weight of a cyclic ether compound copolymerizable with trioxan and (c) 0.001 to 10 parts by weight of a monofunctional glycidyl compound, wherein the monofunctional glycidyl compound (c) has a chlorine content of 0.3 wt % or less. The polyacetal copolymer has excellent impact resistance, rigidity, resistance to creep and the like as inherent properties to the polymer, and also exhibits an improved thermal stability which results in the improved flowability upon molding and the excellent moldability of the polymer.
