ABSTRACT This invention relates to stabilizer compositions for polymers comprising 1) an organotin compound, or mixture of organotin compounds, 2) a mercaptan-containing organic compound or mixture of mercaptan-containing organic compounds, and, optionally, 3) a halogen-containing tin compound or mixture of halogen-containing tin compounds, said stabilizers having a total halogen content of about 0.1% to about 10% by weight based on the weight of the stabilizer composition. This invention also relates to polymer compositions contain- ing said stabilizers, to a process for stabilizing polymer by adding thereto said stabilizers, and to articles of manufacture, e.g. pipe, comprising a polymer and said stabil- izers.
