摘要:
Polyolefins are rendered resistant to degradation upon exposure to heat by incorporating therein a stabilizing amount of a synergistic combination of a phenol-terpene resin, a sulfur-containing secondary antioxidant and a phosphonitrilic composition derived rom a phosphonitrilic halide and certain hydroxy compounds. The above synergistic combination is especially effective for stabilizing polyolefins containing carbon black.
