Abstract:
Polyolefin compositions comprising i) a polyolefin, ii) one or more phosphorus-containing benzofuranone compounds and iii) one or more hindered phenolic antioxidants are provided excellent protection against discoloration and enhanced thermal stability during melt processing as exhibited by improved retention of molecular weight and maintenance of polymer molecular architecture.
