Zusammenfassung:	Stabilization of vinyl chloride polymers and copolymers against heat or light decomposition and composition for use in the practice of same wherein the composition is formed of a solution of a basic lead salt having the general formula (RCOO)2Pb.nPbO, in which R is a branched-chain alkyl radical having from seven to 12 carbon atoms and n is a number of from 0.5 to 2 and in which solution is in a hydrocarbon solvent having a boiling point within the range of 100 DEG to 180 DEG C. or in a plasticizer ester.
