SYNERGISTIC COMPOSITIONS BASED ON ORGANIC SULFIDE COMPOUNDS OF ANTIMONY, ALKALINE-EARTH CARBOXYLATES AND ALKALI METAL CARBONATES FOR THE STABILIZATION OF VINYL HALIDE RESINS AND RESINS STABILIZED THEREFROM
SYNERGISTIC COMPOSITIONS BASED ON ORGANIC SULFIDE COMPOUNDS OF ANTIMONY, ALKALINE-EARTH CARBOXYLATES AND ALKALI METAL CARBONATES FOR THE STABILIZATION OF VINYL HALIDE RESINS AND RESINS STABILIZED THEREFROM
A COMPOSITION FOR STABILIZING A VINYL HALIDE RESIN The composition of the invention contains an organic sulfur-containing molecule of an anti-methanol, e.g. an anti-anthocyanin derivative. A MERCAPTO-ACID ESTER, AN ALKYLMERCAPTIDE, ETC., AN ALKALINE-EARTH METAL SALT OF A CARBOXYLIC ACID, SUCH AS CALCIUM STEARATE, AND AN ALKALI METAL CARBONATE SUCH AS SODIUM CARBONATE. The composition of the invention provides a synergistic contribution to the dynamic stability of compositions based on VINYL HALIDE resins. RIGID COMPOSITIONS BASED ON POLYVINYL CHLORIDE ARE STABILIZED AGAINST DYNAMIC CONDITIONS OF HEAT TREATMENT AND SHEAR EFFORTS. / P
