ELEKTRISCHE KABEL UND MATERIAL ZUM BILDEN DER LEITERUMHUELLUNG

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.
