Method for producing maleic anhydride-modified vinyl chloride resin composition

摘要

PROBLEM TO BE SOLVED: To obtain a maleic anhydride-modified polyvinyl chloride resin composition which is not colored and is modified with maleic anhydride at a high addition rate while suppressing thermal decomposition of polyvinyl chloride and adhesion to a metal. Provide a manufacturing method for. SOLUTION: Polyvinyl chloride, 0.5 to 20 parts by mass of a heat stabilizer with respect to 100 parts by mass of the polyvinyl chloride, and 1 to 30 parts by mass of anhydrous maleine with respect to 100 parts by mass of the polyvinyl chloride. Melt the acid, 0.05 to 5 parts by mass of an organic peroxide with respect to 100 parts by mass of the polyvinyl chloride, and 0.5 to 10 parts by mass of an outer lubricant with respect to 100 parts by mass of the polyvinyl chloride. The content of the compound having at least one functional group selected from the group consisting of a thiol group and a hydroxyl group as the heat stabilizer, which comprises kneading, is 0, based on 100 parts by mass of the polyvinyl chloride. A method for producing a maleic anhydride-modified polyvinyl chloride resin composition, which is less than 01 ppm. [Selection diagram] None
