ABSTRACT:
The heat stability imparted to plasticized vinyl chloride polymers by di- or triesters of phosphorous acid is significantly increased by the addition of 0.1-1% by weight of specified organotin compounds to the polymer composition. The concentration of organotin compound is between 3 and 45%, based on the combined weight of the phosphorous acid ester and organotin compound.
