Polymeric compositions comprising linear polymers united through ionic crosslinkages and through covalent crosslinkages, process for their preparation, and fabrics coated therewith

Claim 1

A REACTION PRODUCT OF (A) A 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 -OPO3H3 GROUPS, AND (B) ASALTS OF SAID LINEAR ACIDIC ORGANIC POLYMERS, WITH (B) A 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 AMINO GROUPS AND QUATERNIZED AMINO GROUPS AND (B) SALTS OF SAID LINEAR ORGANIC POLYMERS CONTAINING AMINO GROUPS, SAID POLYMERS BEING UNITED IN SAID REACTION PRODUCT THROUGH IONIC CROSSLINKAGES, AND BEING FURTHER UNITED THROUGH COVALENT CROSSLINKAGES FORMED BY REACTION OF SAID POLYMERS WITH A MEMBER FROM THE CLASS CONSISTING OF ORGANIC DIISOCYANATES AND 1,2-EPOXY COMPOUNDS.
