Alkali-swellable and alkali-soluble thickeners (asts), as defined herein, are carboxyl functional copolymers produced by the free-radical polymerization of ethylenically unsaturated monomers. The copolymers are substantially insoluble in water at low pH, but exhibit thickening on swelling or dissolution in aqueous media at higher degrees of ionization. In their ionic form (partially or fully neutralized), ASTs generally belong to the broad... [Pg.457]
