Water-insoluble homogeneous polymer blends of a water-insoluble, waterdispersible, nonelectrolyte film-forming polymer with water-soluble linear organic polymers united by ionic crosslinkages, and their preparation, and fabrics coated therewith

Claim 1

A WATER-INSOLUBLE HOMOGENEOUS POLYMER BLEND OF (1) A WATER-INSOLUBLE, WATER-DISPERSIBLE, NONELECTROLYTE FILM-FORMING POLYMER FROM THE CLASS CONSISTING OF POLYMERS OF POLYMERIZABLE ETHYLENICALLY UNSATURATED MONOMERS AND SYNTHETIC LINEAR CONDENSATION POLYMERS FROM THE CLASS CONSISTING OF POLYAMIDES, POLYESTERS AND POLYESTERAMIDES, AND (II) THE REACTION PRODUCT OF (A) A WATER-SOLUBLE LINEAR POLYMER FROM THE CLASS CONSISTING OF (A) LINEAR ACIDIC ORGANIC POLYMERS CONTAINING ATTACHED TO CARBON ATOMS THEREOF A PLURALITY OF GROUPS FROM THE CLASS CONSISTING OF -COOH AND -OPO3H2 GROUPS, AND (B) SALTS OF SAID LINEAR ACIDIC ORGANIC POLYMERS, WITH (B) A WATER-SOLUBLE LINEAR POLYMER FROM THE CLASS CONSISTING OF (A) LINEAR ORGANIC POLYMERS CONTAINING ATTACHED TO CARBON ATOMS THEREOF A PLURALITY OF GROUPS FROM THE CLASS CONSISTING OF TERTIARY AMINO GROUPS AND QUATERNIZED AMINO GROUPS AND (B) SALTS OF SAID LINEAR ORGANIC POLYMERS CONTAINING TERTIARY AMINO GROUPS, SAID WATER-SOLUBLE POLYMERS BEING UNITED THROUGH IONIC CROSSLINKAGES, AND SAID WATER-INSOLUBLE, WATER-DISPERSIBLE, NONELECTROLYTE FILM-FORMING POLYMER BEING AT LEAST 10% BY WEIGHT OF SAID BLEND.
