AN ETHYLENE-BASED COMPOSITION

摘要

The instant invention provides an ethylene-based composition and method of improving stabilization thereof. The inventive ethylene-based composition comprises: (a) a linear low density polyethylene (LLDPE) comprising units derived from ethylene and optionally one or more alpha-olefin comonomers; (b) from 20 to 500 part by weight of a primary antioxidant comprising 3,4-Dihydro-2,5,7,8-tetramethyl-2-(4,8,12-trimethyltridecyl)-2H-1-benzopyran-6-ol per one million parts of LLDPE; (c) optionally from 2 to 200 part by weight of an optical brightening agent; and (d) optionally from 20 to 1000 part by weight of a secondary antioxidant per one million parts of LLDPE.
