Abstract
A surface covering including a blend of a silane-grafted ethylene/vinyl acetate polymer and an ungrafted thermoplastic polymer retains the desirable balance between indentation, tensile strength and elongation of a fully grafted EVA while permitting the reprocessibility of scrap material. Preferably, the silane graft density is one graft per about 100 carbons to one graft per about 5,000 carbons. The preferred EVA has about 18% to about 28% vinyl acetate.
