The present invention relates to high performance wire and cable compositions and to hot melt adhesives containing a silyl-grafted ethylene copolymer having particularly low levels of glycidyl acrylate monomer. The preferred epoxy glycidyl methacrylate copolymerized into the polymer backbone provides a graft site for the aminosilane. Subsequent moisture crosslinking at the silyl site of the thermally stable graft copolymer provides compositions with attractive physical properties for wire and cable semicons, insulation, and jackets, as well as hot melt adhesives. The preferred aminosilane is N-cyclohexylaminopropyl trimethoxysilane.
