Abstract

1462597 Polyurethanes BAYER AG 25 Sept 1975 [28 Sept 1974] 39312/75 Heading C3R Polyurethanes which contain sulphonate groups are prepared by reacting an organic polyisocyanate with a diol preferably having a m.p. of below 120‹ C. and which has the formula wherein A and B, which may be the same or different, each represents a C 1-6 divalent aliphatic hydrocarbon radical, R represents a hydrogen atom, a C 1-4 aliphatic hydrocarbon radical or a phenyl radical, X<SP>(+)</SP> represents an alkali metal cation or an ammonium ion which may be substituted, n and m each represents a number from 0 to 30, o and p are 0 or 1 and q is 0, 1 or 2, in amounts such that the polyurethane has an SO 3 <SP>(-)</SP> group content of 0À1 to 6% by weight. Optionally, at least one other active hydrogen containing compound may be included amongst the reactants. It is particularly preferred to prepare the polyurethanes with simultaneous conversion into aqueous dispersions. A suitable reaction procedure is to react the polyisocyanate, sulphonated diol and optionally an additional polyhydroxyl compound in any order to form a prepolymer, followed by chain extension of this prepolymer in water to form the preferred aqueous dispersion. The aqueous dispersion is particularly suitable for coating textile materials.
