Contribution to the development of thermal stabilization system for vinylidene chloride co-polymers

Selected compounds of phosphorus and tin improve the thermal stability of vinylidene chloride co-polymers. Although offering superior intermediate color stability, incorporation of polyols will result in erratic processing of the PVdC. Combinations rather than individual compounds appear to stabilize PVdC more effectively and an explanation of the stabilization mechanism is attempted for some compounds.
