  • Microporous polyurethane hydrogels, method and composites with natural and other synthetic fibers or films
    Patent number: 3939105
    Abstract: Microporous polyurethane hydrogels of high water swellability comprising lightly crosslinked polymers of isocyanate terminated prepolymers which are the reaction product of (i) poly(alkyleneoxy) polyol with (ii) organic diisocyanate that has been lightly crosslinked with (iii) water or an organic polyamine are produced by impregnating the isocyanato terminated prepolymer solution prior to contact with the crosslinking agent with a minor significant amount of a liquid non-solvent.
