Abstract
Abstract A composite of polymeric materials which are adheringly joined to each other and which can be easily and cleanly separated by stripping apart with a low pulling force whereupon the contacting surfaces of their interface each separate cleanly without retention of any residue from the other, and which comprises the combination of a body of peroxide curable ethylene-containing polymer adjoined to a body of a sulfur curable elastomer comprising chlorosulfonated polyethylene. The combination of materials is especially advantageous when used in wire and cable constructions comprising a composite of an electrical insulation and an overlying strippable semiconductive layer.

Independent Claim
106 words
AN INSULATED METALLIC ELECTRICAL CONDUCTOR HAVING A COVERING THEEON COMPRISING A COMBINATION OF POLYMERIC COMPOSITION INCLUDING A COMPOSITE OF AN ELECTRICALLY-INSULATING BODY OF A PEROXIDE-CURED PRODUCT OF AN ETHYLENE-CONTAINING POLYMER WITH A SURFACE ADHERINGLY JOINED TO A CONTACTING SURFACE OF AN EASILY AND CLEANLY STRIPPABLE OVERLYING SEMI-CONDUCTIVE BODY OF A SULFUR-CURED PRODUCT OF AN ELASTOMER OF CHOROSULFONATED POLYETHYLENE WITH SAID CONTACTING SURFACES OF THE INSULATING BODY AND OVERLYING SEMICONDUCTIVE BODY BEING ADHERINGLY JOINED TO EACH OTHER AS A RESULTOF AT LEAST ONE OF SAID POLYMERIC MATERALS HAVING BEEN CURED WHILE THE SAID SURFACES OF EACH OF THE BODIES ARE IN ADJOINING PHYSICAL CONTACT WITH EACH OTHER.
Claim 2
Dependent Claim
106 words
AN INSULATED METALLIC ELECTRICAL CONDUCTOR HAVING A COVERING THEEON COMPRISING A COMBINATION OF POLYMERIC COMPOSITION INCLUDING A COMPOSITE OF AN ELECTRICALLY-INSULATING BODY OF A PEROXIDE-CURED PRODUCT OF AN ETHYLENE-CONTAINING POLYMER WITH A SURFACE ADHERINGLY JOINED TO A CONTACTING SURFACE OF AN EASILY AND CLEANLY STRIPPABLE OVERLYING SEMI-CONDUCTIVE BODY OF A SULFUR-CURED PRODUCT OF AN ELASTOMER OF CHOROSULFONATED POLYETHYLENE WITH SAID CONTACTING SURFACES OF THE INSULATING BODY AND OVERLYING SEMICONDUCTIVE BODY BEING ADHERINGLY JOINED TO EACH OTHER AS A RESULTOF AT LEAST ONE OF SAID POLYMERIC MATERALS HAVING BEEN CURED WHILE THE SAID SURFACES OF EACH OF THE BODIES ARE IN ADJOINING PHYSICAL CONTACT WITH EACH OTHER.
Claim 3
Dependent Claim
59 words
The insulated metallic electrical conductor of claim 1, wherein the said contacting surfaces of the insulating body and overlying semiconductive body are adheringly joined to each other as a result of both the ethylene-containing polymer and the elastomer of chlorosulfonated polyethylene having been cured simultaneously while the surfaces of their bodies are in adjoining physical contact with each other.
Claim 4
Dependent Claim
28 words

The insulated metallic electrical conductor of claim 1, wherein the electrically insulating body of a peroxide-cured product of an ethylene-containing polymer is polyethylene cured with an organic tertiary peroxide curing agent.
Claim 10
Dependent Claim
139 words
An insulated metallic electrical conductor having a covering thereon comprising, a combination of polymeric Compositions including a composite of an electrically insulating body of a peroxide-cured product of polyethylene and an organic tertiary peroxide curing agent, with a surface thereof adheringly joined to a contacting surface of an easily and cleanly strippable overlying semiconductive body of a sulfur-cured product of an elastomer of chlorosulfonated polyethylene and a sulfur-containing curing agent having an electrically conductive filler dispersed therethroughout in an amount of about 15 to about 75% by weight of the elastomer, said contacting surfaces of the insulating body and overlying semiconductive body being adheringly joined to each other as a result of both the polyethylene and the elastomer of chlorosulfonated polyethylene having been cured simultaneously while the surfaces of their bodies are in adjoining physical contact with each other.
Claim 11
Dependent Claim
139 words
An insulated metallic electrical conductor having a covering thereon comprising, a combination of polymeric Compositions including a composite of an electrically insulating body of a peroxide-cured product of polyethylene and an organic tertiary peroxide curing agent, with a surface thereof adheringly joined to a contacting surface of an easily and cleanly strippable overlying semiconductive body of a sulfur-cured product of an elastomer of chlorosulfonated polyethylene and a sulfur-containing curing agent having an electrically conductive filler dispersed therethroughout in an amount of about 15 to about 75% by weight of the elastomer, said contacting surfaces of the insulating body and overlying semiconductive body being adheringly joined to each other as a result of both the polyethylene and the elastomer of chlorosulfonated polyethylene having been cured simultaneously while the surfaces of their bodies are in adjoining physical contact with each other.
Claim 12
Dependent Claim
48 words
The insulated metallic electrical conductor of claim 9, wherein the semiconductive body of a sulfur-cured product of an elastomer of chlorosulfonated polyethylene includes up to about 20% by weight of at least one ethylene-propylene rubber selected from the group consisting of copolymers and terpolymers of ethylene and propylene.
