ABSTRACT:
The invention relates to bulk polyurethane ionomers prepared by the reaction (A) an isocyanate terminated ionic prepolymer with (B) a hydrocarbon polyol chain extender, said prepolymer having been prepared from (i) an excess of diisocyanate, (ii) a mixture comprising a diol and an organic polyol having three or more reactive hydroxyl moieties each having a molecular weight of from about 250 to about 6,000 and (iii) a difunctional isocyanate-reactive component containing an ionic group or potential ionic group.
