Aluminum salts of esters as stabilizing agents for chlorinated vinyl polymers

Abstract

Abstract COMPOUNDS OF THE FORMULA Q(-CO-OR)N(-CO-OM)M WHEREIN Q IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF ARYL, SATURATED STRAIGHT-CHAINED OR BRANCHED HYDROCARBON OF 2 TO 20 CARBON ATOMS AND UNSATURATED STRAIGHT-CHAINED OR BRANCHED HYDROCARBON OF 3 TO 20 CARBON ATOMS, R IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF ARYL AND SATURATED STRAIGHT-CHAINED OR BRANCHED ALIPHATIC HYDROCARBON OF 2 TO 20 CARBON ATOMS, AND R MAY BE SUBSTITUTED WITH AT LEAST ONE HYDROXY, M IS ONE EQUIVALENT OF ALUMINUM, N AND M EACH REPRESENT AN INTEGER OF 1 TO 3, AND THE SUM OF N+M IS AT LEAST TWO AND NOT MORE THAN FOUR, BUT IF Q IS PHENYL, N MAY NOT REPRESENT 1. HAVE BEEN PREPARED BY REACTING THE ALKALI METAL SALTS OF THE APPROPRIATE PARTIAL ESTERS WITH COMPOUNDS SUPPLYING ALUMINUM. THE COMPOUNDS OF THE GENERAL FORMULA I EXERT EXCELLENT STABILIZING EFFECT ON CHLORINATED VINYL POLYMERS. THE STABILIZERS MAY BE ADDED TO THE POLYMERS IN AN AMOUNT OF 0.1 TO 30% BY WEIGHT, PREFERABLY IN AN AMOUNT OF 1 TO 20% BY WEIGHT. THE NOVEL STABILIZERS CAN BE USED IN ADMIXTURE WITH CONVENTIONAL STABILIZERS AS WELL.
