ABSTRACT:
Hydrolytically stabilized phosphite compositions are provided. The compositions contain an organic phosphite ester antioxidant and a hindered piperidinyl light stabilizer. The hindered piperidinyl component is not only a light stabilizer but also functions to hydrolitically stabilize the organic phosphite antioxidant. The compositions are useful as stabilizer additives to polymeric compositions.
