PRODUCTION OF MOLDED FIBROUS BASIC MAGNESIUM SULFATE FILLER-CONTAINING OLEFIN POLYMER COMPOSITION PRODUCTS

摘要

A molded fibrous basic magnesium sulfate filler-containing olefin polymer composition product is produced by a process comprising the steps of preparing a fibrous basic magnesium sulfate filler-containing master batch composition which comprises an olefin polymer, a fibrous basic magnesium sulfate filler, an elastomer, a fatty acid metal salt and a hydrocarbon or silicone oil or a hydrocarbon or silicone wax; mixing the master batch composition and a propylene polymer-containing diluent resin; kneading the resulting mixture in a molten state; and molding the molten mixture to give the molded product.
