Peroxide-crosslinkable compositions and processes for their manufacture

A peroxide-crosslinkable composition comprising: The composition is useful in the manufacture of insulation sheaths for high and extra high voltage wire and cable.

A peroxide-crosslinkable composition comprising: (A) A peroxide-crosslinkable polymer, e.g., a polyethylene; (B) A nitrogenous base, e.g., a low molecular weight, or low melting, or liquid nitrogenous base such as triallyl cyanurate (TAC); and (C) One or more antioxidants (AO), e.g., distearylthiodipropionate (DSTDP). The composition is useful in the manufacture of insulation sheaths for high and extra high voltage wire and cable.

Thiobis phenolic antioxidants are efficiently dry or melt blended with a tree-resistant, crosslinkable polyethylene by first forming a blend, preferably a dry blend, of the antioxidant with a polyalkylene glycol (PAG), and then mixing the blend with the polyethylene. The incorporation of thiobis phenolic antioxidant and PAG blend into polyethylene provides the PE with high oxidative induction time (OIT) which is a measure of the oxidative stability of the PE.
