Abstract
An additive composition is provided that comprises: (a) tris(3,5-di-tert-butyl-4-hydroxybenzyl)isocyanurate; (b) bis(2,4-di-tert-butylphenyl)pentaerythritol diphosphite; and (c) a costabilizer selected from the group consisting of sodium stearoyl lactylate, calcium stearoyl lactylate, calcium lactate, and mixtures thereof. Additionally, polymer compositions are provided that comprise the additive composition and (a) 2-Naphthalenecarboxamide, N,N′-(2-chloro-1,4 phenylene)bis[4-[(2,5-dichlorophenyl)azo]-3-hydroxy- and (b) a stereoregular, branched-mono-1-olefin polymer.
