Insulation material of non-cross-linked polymer and polymerized silanic monomer and electrical cables insulated therewith

摘要

An electric cable having at least one conductor and at least one covering therefor obtained from the polymerization of a silanic monomer of a compound comprising a non-cross-linked base-polymer and a polymerizable silanic monomer present prior to polymerization in a quantity not less than 5 parts by weight with respect to 100 parts by weight of the base-polymer. Thepolymerization of the silanic monomer units forms a polymeric mesh which is closely interconnected and thoroughly compenetrated into the non-cross-linked base-polymer. In one embodiment the polymeric mesh may be grafted onto the base-polymer through the addition of an organic peroxide. Thus, there is provided an electric cable for use as building wires wherein the conductor covering is not cross-linked but is heat resistant to temperatures above the deformation temperature of the base-polymer.
