The effect of tridecyl phosphite on the stabilization of the thermal degradation of poly(vinyl chloride) under nitrogen by cadmium and zinc stearates has been studied. The rate of evolution of hydrochloric acid from solutions of the polymer with stabilizers in dioctyl phthalate at 190°C has been measured. Tridecyl phosphite absorbs HCl and is converted into the phosphonate which reduced the deleterious action of the cadmium and zinc chlorides formed from the stearates.
