COMPOSITION BASED ON A METAL SALT OF HIGHER FATTY ACID, A POLYHYDROXYL ALCOHOL AND A MAGNESIUM COMPOUND, FOR STABILIZING A VINYL HALIDE RESIN AND RESIN STABILIZED WITH THAT COMPOSITION
COMPOSITION BASED ON A METAL SALT OF HIGHER FATTY ACID, A POLYHYDROXYL ALCOHOL AND A MAGNESIUM COMPOUND, FOR STABILIZING A VINYL HALIDE RESIN AND RESIN STABILIZED WITH THAT COMPOSITION
The invention relates to the field of chemistry of plastics. It relates to a composition intended to stabilize a resin of the type VINYL HALIDE, COMPRISING A SALT OF CA, ZN OR CAZN A HIGHER FATTY ACID, A POLYHYDROXYLIC ALCOHOL FORMED AT AT LEAST 50 OR TRIPENTAERYTHRITOL, AND A MG COMPOUND, IN PARTICULAR HYDROXIDE OR MG ACETATE. THE INVENTION CONTRIBUTES BY THEIR SYNERGISTIC EFFECT TO STABILIZE VINYL HALIDE RESINS IN RELATION TO HEAT. SHORT-TERM COLOR CHANGE BEHAVIOR AND LONG-TERM THERMAL STABILITY OF METAL SALTS IS IMPROVED IN THE COMPOSITIONS OF THE INVENTION, WHICH ALLOWS ECONOMIC REDUCTION OF THE NECESSARY QUANTITIES OF THESE COMPOUNDS WITH A VIEW TO STABILIZATION. / P
