Abstract
The invention is directed to stabilizer compositions, to polymers containing these stabilizer compositions for use as additives in polymeric matrices, and to polymeric products which contain these additives. The stabilizer compositions comprise a ternary composition of a sterically hindered phenol, a less sterically hindered phenol, and an organic phosphite. These compositions are admixed with polymers to provide polymeric additives to improve the physical and mechanical properties of polymeric matrices.
