Thiobisphenolic antioxidants and tri-resistant crosslinkable polyethylenes are efficiently dried or melted by first forming a blend of antioxidants and polyalkylene glycol (PAG), preferably a dry blend, and then mixing the blend with polyethylene. Blended. Incorporating a blend of thiobisphenolic antioxidants and PAG into polyethylene gives PE a high oxidation induction time (OIT), which is an indicator of its oxidative stability. |
