Abstract:
A composition comprising:(a) one or more copolymers selected from the group consisting of (I) a copolymer of ethylene and of vinyl acetate containing about 10 to about 50 percent by weight of units of vinyl acetate and having a melt mass flow rate of about 1 to about 100 grams per 10 minutes; (II) a copolymer of ethylene and ethyl acrylate containing about 10 to about 50 percent by weight of units of ethyl acrylate and having a melt mass flow rate of about 1 to about 100 grams per 10 minutes; and (III) a copolymer of ethylene and butyl acrylate containing about 10 to about 50 percent by weight of units of butyl acrylate and having a melt mass flow rate of about 1 to about 100 grams per 10 minutes; (b) about 55 to about 200 parts by weight, based upon 100 parts by weight of component (a), of a linear copolymer of ethylene and an alpha-olefin having 3 to 12 carbon atoms, the linear copolymer of ethylene having a melt mass flow rate of about 0.1 to about 30 grams per 10 minutes and a density of 0.870 to 0.944 gram per cubic centimeter; (c) about 1 to about 50 parts by weight, based upon 100 parts by weight of component (a), of an organopolysiloxane having the following formula: R1xR2ySiO(4-a-b)/2 wherein R1 is an aliphatic unsaturated hydrocarbon group; R2 is selected from the group consisting of alkyl, substituted alkyl, aryl, substituted aryl, hydrogen and mixtures thereof, wherein the substituents of the substituted alkyl and substituted aryl are selected from the group consisting of halogen, cyano and mercapto; x is equal to or greater than 0 but less than 1; y is greater than 0.5 but less than 3; x+y is greater than 1 but less than 3; a is greater than 0 but equal to or less than 1; and b is equal to or greater than 0.5 but equal to or less than 3; (d) about 10 to about 350 parts by weight, based upon 100 parts by weight of component (a), of carbon black; and (e) from 0 to about 2 parts by weight of an organic peroxide, the composition effective for being cross-linked, without a catalyst, with water to provide a cross-linked composition.
