The reaction of a model compound for degrading PVC, cinnamyl chloride, with blends of antimony tris(isooctyl thioglycolate) and calcium octoate yields primarily calcium chloride and cinnamyl octoate. This is in contrast to typical mixed metal systems where ligands exchange, and also to lead octoate/calcium octoate blends, where lead chloride is formed under the same conditions. In rigid PVC, it is likely that antimony mercaptides function as stabilizers mainly by acting as phase transfer catalysts for calcium stearate.
