Abstract
The invention includes a water-curable azidosilane grafted polymer selected from the group consisting of (i) homogeneous ethylene polymers which has a density less than or equal to about 0.900 g/cm.sup.3, and (ii) interpolymers of at least one ethylene or .alpha.-olefin and at least one vinylidene aromatic compound. The water-curable silane-grafted polymer may comprise the reaction product of: at least one first polymer, the first polymer selected from the group consisting of an interpolymer, a substantially linear ethylene polymer, and a mixture thereof; the interpolymer comprising polymer units of at least one ethylene or .alpha.-olefin and at least one vinylidene aromatic compound; and at least one monofunctional azidosilane. The invention further includes a process for producing a water-curable silane-grafted polymer. A further embodiment of the process of the invention comprises shaping the water-curable silane-grafted polymer and contacting the shaped water curable silane-grafted polymer to form a moisture-cured polymer. The invention also includes the water curable silane-grafted polymers produced by either of the two processs along with any articles obtainable from that wat…
