ABSTRACT:
Homogeneous storage-stable liquid stabilizer systems for polyvinyl chloride resins 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 ingredients, a liquid barium carbonate-barium alkyl phenate; a cadmium salt of a branched chain C.sub.5 to C.sub.13 aliphatic carboxylic acid and/or of an aromatic C.sub.7 to C.sub.11 carboxylic acid and/or of C.sub.12 to C.sub.22 unsaturated aliphatic carboxylic acid; and a liquid organic triphosphite in an amount to form a homogeneous storage-stable liquid; the total weight percent of barium and cadmium in the stabilizer system being at least 13%, and the ratio of the weight percent of cadmium to the weight percent of barium being within the range from about 0.5:1 to about 1.5:1; optionally together with any one or more of a soluble zinc salt of a carboxylic acid, a soluble phenolic antioxidant, a liquid organic acid phosphite, and a soluble carboxylic acid.
