  • Copolymer having quaternary ammonium, n-alkoxyalkyl amido, and carboxy groups, optionally epoxy resin, and aqueous dispersions
    Patent number: 4012353
    Abstract: Cationic, cross-linkable acrylic-polyester emulsion binder resin systems are described which are useful as adhesives for binding organic, metal, and glass filaments to each other and to various substrates in the preparation of reinforced composites. These novel binder resin systems are derived from copolymerized ethylenically unsaturated monomers having pendant non-functional, cross-linking functional, and cationic groups. The cationic polymer emulsions are particularly useful when they are cross-linked with polyester resin polymer chains such as those formed by condensing unsaturated dicarboxylic acids with polyols and which can be applied as stable aqueous emulsions.
