    摘要: A process for preparing non-ionic polyurethane emulsions comprising chain-extending (A) an isocyanate-terminated urethane prepolymer (formed by reaction of a polyhydroxyl reactant having a molecular weight of 200 to 10,000 and a stoichiometric excess of a polyisocyanate), with (B) a polyalkylene polyamine as chain extending compound, thereby to form a polyurethane-urea polyamine product, mixing the said polyamine product with water or reacting the product with a cyclic dicarboxylic acid anhydride and then mixing the reaction product with water; said process being characterized in that a water-soluble polyoxyethylene glycol comprises 15 to 80% by weight of the polyhydroxyl reactant, and the said polyalkylene polyamine used as the chain-extending compound has at least two primary or secondary amino groups and a functional group having the formula --CH(OH)--CH.sub.2 X in which X is Cl or Br.

    摘要: A process for the preparation of anionic resinous aqueous emulsions useful for the treatment of fiber-containing products, comprising reacting an isocyanate-terminated urethane prepolymer with an excess of a polyalkylene polyamine to form a polyurethane-urea-polyamine, then reacting a part of the amino groups in the polyurethane-urea-polyamine with a compound selected from the group consisting of alkyl isocyanates in which the alkyl group has 12 to 22 carbon atoms and alpha-olefin epoxides having 12 to 22 carbon atoms, thereby to introduce a long-chain alkyl group into the molecule, reacting the thus-formed product having some unreacted amino groups with a cyclic dicarboxylic acid anhydride, and mixing the resulting reaction product with an aqueous solution of a basic substance.
