Abstract

The invention relates to a composition containing organotin maleates such as is obtained by reacting a mixture of a low molecular weight alcohol or epoxyalkane and of a high molecular weight alcohol or epoxyalkane with maleic anhydride and by then bringing the mixture thus obtained into contact with a dialkyltin oxide. The invention also relates to poly(vinyl chloride) (PVC) composition stabilized and lubricated using the said composition based on organotin maleates and also to the extruded rigid objects formed from the said PVC compositions.
