<p>A method for stabilizing a polyethylene composition, such as a linear low density polyethylene, against degradation, by incorporating into the polyethylene composition, an effective stabilizing amount of a stabilizing composition of: (a) a pentaerythritol diphosphite; and (b) an antioxidant compound selected from the group consisting of: (i) at least one diphenylamine selected from the group consisting of alkyl-substituted diphenylamine and aralkyl-substituted diphenylamine; (ii) at least one sterically hindered phenol; and (iii) a combination of (i) and (ii). Stabilized polyethylene compositions are also described which have the above-described stabilizing composition incorporated therein.</p> |
