Abstract
Homogeneous liquid stabilizer systems imparting to polyvinyl chloride resins a heat and light stability comparable to or exceeding organotin stabilizers are provided which are substantially solvent-free and have a low viscosity and a minimum flash point of 96.degree. C., containing as the essential and only stabilizers a liquid barium carbonate-barium alkyl phenate and a cadmium salt of a branched chain aliphatic carboxylic acid having from about eight to about ten carbon atoms, optionally as a mixture of at least 85% cadmium salt of a branched chain aliphatic carboxylic acid with up to about 15% of a cadmium salt of an aromatic carboxylic acid having from about seven to about eleven carbon atoms, and/or of a saturated or unsaturated straight chain aliphatic carboxylic acid having from about nine to about twenty-two carbon atoms, the total weight percent of barium and cadmium in the stabilizer system being at least 18%, and the ratio of the weight percent of cadmium to the weight percent of barium being within the range from about 0.4:1 to about 1.2:1.
