ABSTRACT: Novel compositions and use therefore as stabilizers during the production of vinyl halide resins are disclosed which comprise antimony mercaptides having the general formula: Image wherein K is 1 to 4; L is 0 to 1; M is 1 to 4; N is 1 to 4; X is oxygen or sulfur; and R is an alkyl, alkenyl, alkynyl having 1 to 18 carbon atoms and combinations thereof. Such compositions when used during vinyl halide resin processing retard discoloration and mechanical degradation at least as effectively as previously known antimony mercaptides while being more economical to produce.
