Beschreibung
Zusammenfassung:	A resilient surface covering, including a melt-processed layer, having improved impact resistance properties is provided herein. The melt-processed layer is formed, in part, of either a non-polyvinyl chloride resin, or a blend of a polyvinyl chloride resin and a compatible polymer, such as nitrile rubber, which imparts improved toughness characteristics to the layer. The increased toughness of the melt-processed layer consequently imparts improved impact resistance to the surface covering of which it is a part as compared to a control surface covering having a control layer formed only of a conventional melt-processed polyvinyl chloride resin.
