ABSTRACT:
Halogenated vinyl resins such as poly(vinyl chloride) (P.V.C.) are stabilized against degradation by the addition of stabilizers comprising specified monoorganotin sulfur-containing compounds, for example the reaction product of a mono-organotin tris mercapto carboxylic acid ester and a di-organotin sulfide in combination with an alkyl, aryl or mixed alkyl-aryl ester of phosphorous acid. Preferably the stabilizers also include a hindered phenol.
