Abstract
Abstract This invention comprises novel compositions of matter for use as stabilizers for polyvinyl chloride resins. These compositions comprise alkali metal soap and/or phenolate complexes or solutions (sodium and potassium preferred) and alkaline earth metal soap and/or phenolate complexes or solutions with soluble zinc chloride and hydroxy compounds (or other suitable solutions of zinc chloride) and organophosphites. These combinations of materials have not previously been described as useful for these purposes.
