Document Type and Number:
Japanese Patent JP7223799
Kind Code:
B2
Abstract:
Provided is a production method for a polyacetal resin composition containing prescribed amounts of each of: (B) a prescribed modified olefin polymer, (C) a prescribed alkylene glycol polymer, (D) a prescribed calcium carbonate, (E) a partial ester of a polyhydric alcohol which is at least dihydric and at most tetrahydric, and (F) an alpha olefin oligomer, relative to 100 mass% of (A) a polyacetal copolymer obtained by adding a basic deactivating agent (d) to the reaction product from performing polymerization with trioxane as a main monomer (a), a cyclic ether and/or a cyclic formal having at least one C-C bond as a co-monomer (b), and a prescribed heteropolyacid utilized as the polymerization catalyst (c), then performing melt-kneading, and deactivating the polymerization catalyst (c).
