Abstract
Novel polyacrylic acid resins are prepared by polymerizing H.sub.2 C.dbd.CHCO.sub.2 H, H.sub.2 C.dbd.CRCO.sub.2 X, or HRC.dbd.CHCO.sub.2 X, wherein R is an aliphatic or aromatic hydrocarbon, halogenated hydrocarbon, or sulfonated hydrocarbon of from C.sub.1 to C.sub.20, phenol, naphthol, sulfonated phenol, sulfonated naphthol, or a halogen, and X is hydrogen, alkyl, or a hydroxylated, ethoxylated, sulfonated, or halogenated aliphatic or aromatic hydrocarbon of from C.sub.1 to C.sub.20, sodium, potassium, ammonium, or quaternary amine, in the presence of aromatic sulfonic acid or its salt to form a polymer in which the sulfonated aromatic compound is covalently bound to the polymer. In an alternative embodiment, a textile processing or cleansing compound is included in the polymerization reaction along with the acrylic acid and aromatic sulfonic acid or its salt. The resulting polymers have superior properties for use in textile processing and cleaning, and can be used as detergents, acid dye levelers, surfactants, emulsifiers, yarn lubricants, copolymerizing agents, polymer after treat agents, defoamers, chelating agents, flocculants, anti-static agents, flame retardants, metal cleaners, metal coatings, and as multipurpose acids.
