    摘要: For a flame retardant came, it has been surprisingly found that an insulated conductor, having at least two insulation layers, a composite dielectric constant less than or equal to 2.6, and a composite dissipation factor less than or equal to 0.005, can be prepared even though one of the insulation layers has a dielectric constant greater than 2.6 or a dissipation factor greater than 0.005. It has also been surprisingly found that an insulated conductor, having a composite dielectric constant less than or equal to 2.6 and a composite dissipation. factor less than or equal to 0.005, can be prepared with a non-halo-enated polyolefin as an insulation layer polymer, where the polyolefin having relatively poor dielectric/dissipative properties and the insulation layer composition being substantially free of halogenated or antimony trioxide flame retardant additives.

    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.
