Abstract

1460685 Polyurethanes BAYER AG 29 July 1975 [1 Aug 1974] 31680/75 Heading C3R [Also in Division C2] Polyurethanes are obtained by the polyaddition reaction of at least one polyol and a polyisocyanate mixture stabilized against mono - mer reversion and based on tris-(isocyanatohexyl)-biuret and its higher homologues, containing from 1 to 36% by weight, based on the polyisocyanate mixture, of N-formyl urea groups of the formula
