Novel polyacrylic acid resins are prepared by polymerizing H2C=CHCO2H, H2C=CRCO2X, or HRC=CHCO2X, wherein R is an aliphatic or aromatic hydrocarbon, halogenated hydrocarbon, or sulfonated hydrocarbon of from C1 to C20, 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 C1 to C20, 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, surfactans, 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.

Nouvelles résines d'acide polyacrylique, préparées par polymérisation de H2C=CHCO2H, H2C=CRCO2X ou HRC=CHCO2X, dans lesquels R est un hydrocarbure aliphatique ou aromatique, un hydrocarbure halogéné, un hydrocarbure sulfoné C1 à C20, un groupe phénol, naphtol, phénol sulfoné, naphtol sulfoné ou un halogène, X est de l'hydrogène, un alkyle ou un hydrocarbure aliphatique ou aromatique, hydroxylé, éthoxylé, sulfoné ou halogéné de C1 à C20, du sodium, du potassium, de l'ammonium ou une amine quaternaire, en présence d'un acide aromatique sulfonique ou de son sel, formant un polymère dans lequel le composé aromatique sulfoné est lié par covalence au polymère. Dans une autre réalisation de l'invention, un composé de nettoyage ou de traitement de produits textiles est inclus dans la réaction de polymérisation avec l'acide acrylique et l'acide aromatique sulfonique ou son sel. Les polymères obtenus ont des propriétés supérieures pour le nettoyage et le traitement des produits textiles et peuvent servir comme détergents, agents d'unisson pour colorants acides, surfactifs, émulsifiants, lubrifiants pour fils, agents de copolymérisation, agents post-traitement pour polymères, antimousses, agents chélateurs, floculants, agents antistatiques, ignifugeants, nettoyants ou revêtements pour métaux, et acides à usage multiple.
