Abstract: There is described a polyurethane anionomer which is particularly suitable as a textile sizing agent because it is water-soluble and sufficiently hydrolysis-resistant to be recoverable by ultra-filtration. It is superior to previously known ionomers in being hard, tough and having a smooth surface.This anionomer is produced by reacting organic diisocyanates with tri- or tetra-ethylene glycol and optionally other aliphatic glycols as well as glycols bearing carboxyl, carboxylate, sulphonic acid or sulphonate groups in selected ratios which render the anionomer water-soluble after neutralization of an appropriate amount of the carboxyl or sulphonic acid groups. Aqueous solutions can be formed by dissolving the solid anionomer in water and these solutions can be used to size textile fibers with the recovery of excess anionomer by ulra-filtration.

Abstract: This disclosure teaches synthetic polyurethane sponges manufactured with at least 4% of one or more additives dispersed therein. The additives may be soap, lotions, detergents, pesticides, lanolin, scouring particles, silicone oils, bath oils, or the like or combinations thereof. The sponges' skeletons are developed by reaction of a polyether or a polyester with a suitable isocyanate in the presence of a catalyst with the additives entrapped in voids of the sponges. An additive bearing material, i.e. a carrier material containing the additive is prepared. The carrier material is then mixed into a foam forming reaction mass. By this expedient the additive does not impair desired foam formation. The sponges are provided with high liquid absorbency and fine "hand" by virtue of manufacturing methods and specific catalysts employed.
