Abstract: Organic thiol compounds based on pentaerythritol and dipentaerythritol are described herein. More specifically, the compounds of the present invention are mixed esters of pentaerythritol and dipentaerythritol having at least one sulfhydryl group and preferably a plurality of sulfhydryl groups as well as at least one non-thiol-containing group. The organic thiol compounds are utilized to plasticize and/or heat stabilize halogen-containing polymer compositions especially poly(vinyl chloride) compositions. The compositions are substantially free or free of metal-based stabilizers, Lewis acids and terpenes. The compounds of the present invention are ideally utilized in polymers normally susceptible to deterioration and color change which can occur during processing of the polymer or exposure of the polymer to certain environments and surprisingly also serve as excellent plasticizers.
