Abstract

Cette invention se rapporte à des compositions de stabilisateurs liquides, qui sont utiles dans des formulations de chlorure de polyvinyle et qui possèdent une tendance réduite à former des précipités avec le temps, ces compositions comprenant un ou plusieurs alcool d'éther aromatique représentés par la formule (1): Ar-O-(CH2CH(X)O)nH, où Ar représente aryle, X représente -H ou -CH3, et n est compris entre 1 et 5; ainsi qu'un ou plusieurs thioglycolates représentés par la formule (2): (R<1>)aSn(-SCH2COOR<2>)4-a, où R<1> représente alkyle C1-4, a est égal à 1 ou à 2 et R<2> représente alkyle C7-16.
