1. A process to boost a stabilizer in a heat and/or color-stabilized PVC resin composition wherein at least one compound of
the formula ![]() is added to the PVC resin composition, wherein M is a metal, and R is selected from the group consisting of substituted, linear or branched, alkyl, cycloalkyl, aryl, alkaryl, and aralkyl moieties, the substituents comprising at least one or more electron-withdrawing groups, and the PVC resin composition comprising a (co)stabilizer comprising one or more compounds selected from the group consisting of phosphites, epoxides, polyols, enamines, betadiketones, dihydropyridine, beta-ketocarboxylic acid esters, uracils and β-aminocrotonic acid esters, Zn not being present in said PVC resin composition. |
