Abstract
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 tiller-containing master batch composition which comprises an olefin polymer, a fibrous basic magnesium sulfate filler, an elastomer, a specific lubricant and a specific filler-surface treating agent; 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.
