POLYACETAL COPOLYMER AND METHOD OF MANUFACTURING THE SAME

POLYACETAL COPOLYMER AND METHOD OF MANUFACTURING THE SAME

Provided is a method of manufacturing a polyacetal copolymer including: a step of copolymerizing 100 parts by mass of trioxane (A), 0.05 to 5 parts by mass of a cyclic acetal compound (B), and 0.001 to 1 parts by mass of an aliphatic glycidyl ether compound (C) having a chlorine content of 1 to 500...

description Provided is a method of manufacturing a polyacetal copolymer including: a step of copolymerizing 100 parts by mass of trioxane (A), 0.05 to 5 parts by mass of a cyclic acetal compound (B), and 0.001 to 1 parts by mass of an aliphatic glycidyl ether compound (C) having a chlorine content of 1 to 500 mass ppm, in the presence of a linear formal compound (D) as a molecular weight regulator, in which in the step, when a total mass (g) of the trioxane (A), the compound (B), and the compound (C) is "a", a molar number of the linear formal compound (D) is "b", and total molar numbers of water and methanol contained in the trioxane (A), the compound (B), and the compound (C) are respectively "c" and "d", setting is performed to satisfy (b+c+d)/a=1.5 to 7 μmol/g.
