Beschreibung
Zusammenfassung:	This invention is a polyurethane composition useful for backing textiles comprising the catalyzed reaction product of a polyurethane-forming composition which comprises: (A) a first polyol which comprises a relatively high equivalent weight polyol containing an average of about 1.4-1.95 hydroxyl groups per molecule, of which hydroxyl groups at least 30% are primary hydroxyls or a mixture thereof with at least one additional relatively high equivalent weight polyol containing at least 2.05 hydroxyl groups per molecule, of which at least 30% are primary hydroxyls; (B) a relatively low equivalent weight compound having about 2 active hydrogen containing moieties per molecule; (C) a polyisocyanate and (D) a catalytic amount of a catalyst for the reaction of a polyol and a polyisocyanate, wherein the functionalities and proportions of components (A), (B), and (C) are such that such components have an average functionality of about 1.97-2.03, and the composition has an isocyanate index of about 85 to about 125. This invention is also a textile having attached on one side thereof a adherent polyurethane backing, which backing is prepared from the above-described polyurethane-forming composition.
