The mechanics of arteiole-interstitium interaction

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 separate cleanly without retention of any residue on one from the other, and which comprises the combination of a previously cured body of a copolymer of ethylene and propylene adjoined to a subsequently cured body of an elastomeric blend of a copolymer of ethylene and propylene admixed with chlorosulfonated polyethylene. The combination of materials is especially advantageous when used in electrically conducting wire and cable constructions as a composite of an electrical insulation and an overlying strippable semiconductive layer.
