Abstract
Disclosed herein is a stabilizer mixture for modifying an olefin-based polymer, which comprises at least one organic phosphorus-containing antioxidant represented by a formula selected from the group consisting of formulae (1), (2), (3), (4), (5), (6), (7), and (8), as well as at least one sulfur-containing carboxylate salt represented by a formula selected from the group consisting of formulae (9), (10), (11), and (12). Also disclosed herein is a modified polymer composition prepared from an olefin-based polymer using the stabilizer mixture. The olefin-based polymer is selected from the group consisting of polyolefin, ethylene-vinyl acetate copolymer, and a combination thereof.
