    摘要： A process is described for the preparation of predominantly linear polyurethane solutions which comprises(a) reacting(A) an organic diisocyanate or diisocyanate mixture optionally containing small portions of a triisocyanate with(B) one or more polyhydroxyl compounds which are predominantly bifunctional and generally have molecular weights of from about 400 to 5000 and(C) optionally one or more chain lengthening agents having at least two isocyanate reactive hydrogen atoms and molecular weights of from about 32 to 399, wherein the proportion of isocyanate groups to the number of isocyanate-reactive hydrogen atoms is in the range of from about 0.9:1 to 1:0.9, and(b) when the polyurethane formed has reached the required viscosity, adding a monofunctional, low molecular weight oxime having a molecular weight of from about 73 to 325, preferably butanone oxime, to the reaction mixture as chain breaking agent in a quantity equivalent to or in excess of the equivalents of unreacted isocyanate groups.The new chain breaking agents are simple compounds which effect rapid chain breaking and have no undesirable side effects as regards subsequent breakdown of the chains and even enable further synthesizing reactions to be carried out if desired, for example with diamines.

    摘要： This invention relates to a process for the production of water dispersible polyurethanes by reacting polyisocyanates with sulphonate group containing diols. The sulphonate diols have the general formula: ##STR1## WHEREIN A and B, which may be the same or different, each represents a divalent aliphatic hydrocarbon group containing from 1 to 6 carbon atoms,R represents hydrogen, an aliphatic hydrocarbon group containing 1 to 4 carbon atoms or a phenyl group,X.sup.(+) represents an alkali metal cation or ammonium group which may be substitutedn and m, which may be the same or different, each represents an integer between 0 and 30 inclusive,o and p, represent 0 or 1, andq represents an integer of 0 or 2.Sufficient amounts of this diol are used to provide the final polymer with a sulphonate group content of about 0.1 to 6 wt.%. In a preferred embodiment, a prepolymer is formed in substance with the sulphonate bearing diol, the polyisocyanate and optionally other reactive hydrogen bearing compounds. The prepolymer is then chain extended with water and water soluble polyamines. This second stage may take place in water and the polyamines may carry sulphonate groups.
