摘要
Preparation of thin-walled polyurethane elastic moulded articles comprises dipping a moulding body in to an aqueous polyurethane latex preparation, coagulating the latex on the surface of the body, optionally washing and curing, and then separating the layer from the body. A layer of electrolyte as coagulant is generated on the surface of the moulding body; the latex being diisocyanate and a polymeric diol of molecular weight 500-5000, containing ionogenic groups and being of average particle size 50-300 nm. Also claimed are: (a) obtained articles; and (b) aqueous dispersions of water insoluble polyurethane.
