Abstract: Organopolysulfides such as organodisulfides, organotrisulfides and/or organotetrasulfides are useful stabilizers for polymer compositions, wherein the tendency of a polymer to degrade when exposed to environmental conditions such as heat, light and oxygen may be ameliorated by the incorporation of one or more of such organopolysulfides, optionally together with one or more additional stabilization additives such as a hindered phenol antioxidant, phosp(on)ite stabilizer or hindered amine light stabilizer.
