Novel compositions and a stabilized polyvinyl chloride resin composition comprising essentially, in a predominant amount, a polyvinyl chloride resin and, in a small amount, at least one boron-containing organotin compound having the formula WHEREIN R is a member selected from the group consisting of alkyl alkenyl, aralkyl, alkylaryl and aryl; X1 is a member selected from the group consisting of the residues of monomercapto compounds, dimercapto compounds and polymercapto compounds, said residues containing at least one free sulfhydryl radical; and X2 and X3 are members selected from the group consisting of hydroxyl, the same residues as X1, the residues of carboxylic acids and maleic acid monoesters, and the residues of mercapto compounds containing no free sulfhydryl radical.
