COMPOSITION COMPRISING CHLORINE-CONTAINING RESIN

摘要

PROBLEM TO BE SOLVED: To obtain an additive capable of further improving long-lasting thermal stability of chlorine-containing resin, because, even though a technology in which a zeolite-based compound is added to chlorine-containing resin, the chlorine-containing resin containing a zeolite-based compound has rather insufficient long-lasting thermal stability to severe heat history in molding. SOLUTION: This chlorine-containing resin composition excellent in long- lasting thermal resistance is obtained by compounding both an organotin maleate-based compound and a dolomite-based compound surface-treated with a specified compound in a chlorine containing resin.
