A vinyl chloride polymer composition comprising a zinc pyrithione and an effective amount for stabilization of the biocide of a mixed metal (e.g., magnesium/aluminum or magnesium/aluminum/zinc) hydroxycarbonate (or "hydrotalcite"). A pre-blend of the biocide and hydroxycarbonate stabilizer is also described.
