1. Compositions based on vinyl chloride polymer, heat-stabilised by using one or more organic salts of calcium, barium, zinc, cadmium or magnesium, if appropriate a linear polyol having at least four hydroxyl groups of which at least one is a primary alcohol group, and if appropriate an epoxide compound such as, for example, epoxidised soya oil, characterised in that they contain one or more organic compounds of the general formula : see diagramm : EP0004826,P9,F1 in which R1 represents an alkyl radical having from 1 to 36 carbon atoms or an aryl radical, and in which R2 represents an alkyl or alkenyl radical having from 1 to 36 carbon atoms or an aryl radical, it being possible for these radicals to be substituted by one or more halogen atoms, alkyl radicals, hydroxyl, ether or alkoxycarbonyl groups, groups of the formula see diagramm : EP0004826,P9,F2 or nitrogen-containing groups. |
