Abstract
Abstract A composition for bonding to copper comprised of copolymers and ionic copolymers of ethylene and an α,β-monoethylenically unsaturated carboxylic acid having incorporated therein a copper deactivating amount of a copper stabilizer or deactivator. The composition has improved moisture-resistant bond strength on copper and laminates of copper and the composition may be employed as a protective sheathing for cables.
