    摘要: Compositions including a polymer, a primary antioxidant, a secondary antioxidant, and a metal deactivator selected from at least one of 2,2′-oxamido bis[ethyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate] and oxalyl bis(benzylidenehydrazide), are disclosed. The compositions can also include a light stabilizer. The compositions can be used to manufacture insulations for wire and cable. The compositions have improved long-term heat aging and also retain their color when exposed to heat. A method of making an insulation for a conductor, such as a wire or a cable, made from a composition is also provided.

    摘要: An improved process for crosslinking a polyolefin polymer is described. The process involves grafting a silane material onto the polyolefin based polymer in the presence of a free radical generating initiator material and then hydrolyzing the silane material to form crosslinks. By using an effective molar ratio of silane material to free radical of 40 or greater in the grafting reaction, premature crosslinking is controlled and the grafted polymer can be shaped first and then crosslinked. In another aspect of the invention, the crosslinking process is improved by adding a catalyst for the hydrolysis catalyst to the surface of a shaped article made from the grafted polymer. Grafted polymer and articles made from the grafted polymer, particularly fibers, are also disclosed.
