<p>The compositions comprise: - a) at least one organic zinc derivative, - b) at least one organic derivative of a metal of group 2a of the Periodic Classification, - c) at least one polyol, - d) at least one ester of thioglycolic acid. It also relates to a process for stabilising polyvinyl chloride-based polymers with such stabilising compositions and to the stabilised polymers obtained. Shaped colourless and transparent objects are obtained from the polymers thus stabilised.</p> |
