The present invention is an adhesive composition for stabilizing an electrical conductor. The adhesive composition includes a base polymer and an additive for absorbing UV light, such as a benzotriazole or a benzophenone. When the adhesive composition is in contact with the electrical conductor, the electrical conductor has less than about a 20% change in electrical resistance over a period of about 500 hours.

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.

An ethylene-vinyl alcohol copolymer composition contains: (A) an ethylene-vinyl alcohol copolymer; (B) an antioxidant; and (C) a sorbic acid ester; wherein the sorbic acid ester (C) is present in an amount of 0.00001 to 10 ppm based on the weight of the ethylene-vinyl alcohol copolymer composition; wherein the weight ratio (B)/(C) of the antioxidant (B) to the sorbic acid ester (C) is 500 to 1,000,000. The resulting ethylene-vinyl alcohol copolymer composition is less susceptible to coloration.
