Zusammenfassung:	STABLIZATION OF PVC BODIES The epoxy resin stabilizing systems in combination with cadmium containing stabilizers employed in PVC compounds are replaceable without affecting other properties of the polymer by utilizing a specific additive mixture. In particular, a complex ester of oleic acid and a diglycerol ester of oleic acid are employed in conjunction with a calcium-zinc composition. The resulting system yields excellent processing and long-term stability without significantly affecting other properties such as color stability and flame retardancy.
