CATIONIC, CROSS-LINKABLE ACRYLIC-POLYESTER RESIN BINDER SYSTEMS

摘要

Cationic, cross-linkable acrylic-polyester emulsion binder rosin 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, crosslinking functional, and cationic groups. The cationic polymer emulsions are particularly useful when thery 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.
