<p>Improved, moisture-curable, melt-processible, ethylene copolymer based adhesive compositions which have both specific and broad substrate adhesivity are obtained. The compositions are grafted ethylene copolymers which contain both a carbonyl group in the main chain and an alkoxysilane group in the graft. To use the composition as an adhesive which has elevated temperature utility, one substrate must either contain a silane condensation catalyst, or be pre-treated with such a catalyst, or the adhesive composition itself must contain a low level of such a catalyst. The composition, and the process of using it, are specifically useful in adhering PVC or polyester to wood or glass, and generally useful in adhering a broad range of polymeric substrates to each other.</p> |
