Description

ABSTRACT:
Vinyl and vinylidene halide resins containing carboxyl or sulfonic acid functionalities can be formulated as stable, aqueous, colloidal dispersions by converting them to ionomers in a mixture of water-miscible base, water, organic water-miscible macromolecular compound, water-miscible organic solvent having an affinity for the resin and water-miscible organic co-solvent which is a poor solvent for the resins and a water-immiscible organic diluent, stripping the resultant colloidal dispersion to a total organic solvent content of about 0.2 to about 20% by volume and finally mixing the colloidal dispersion with an acrylic internally crosslinked rheology modifier.
