CA 2002574

ABSTRACT Disclosed are novel stable aqueous dispersions of ionic polyurethane-polyureas prepared from (A) aqueous dispersions of isocyanate terminated ionic prepolymers and (B) hydrocarbon polyamine extenders. The essential feature of the present invention resides in employing a mixture of a diol and triol in the prepolymer forming step. Also disclosed are the films and coated substrates obtained through the use of said dispersions as coatings. The films are useful in the manufacture of waterproof clothing, tarpaulins, chip-resistant coatings in automotive applications and the like.
