Abstract:
A composition comprising:an ethylenically unsaturated acid selected from itaconic, fumaric, maleic, citraconic, acrylic, methacrylic, and cinnamic, itaconic acid monomethylester, vinylphospohonic acid, mesaconic acid, sorbic acid, and vinyl sulphonic acid, and mixtures thereof, and a polyamine wherein the composition has a crosslinker reacted therein and in the said polyamine has four or more A, B, or C units, where: A is an â€”R2â€”N(R1)2 unit, B is an â€”R1â€”N(R2â€”)2 unit, and C is an (â€”R2)3Nâ€” unit, where: R1 is independently selected from hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl, and alkylaryl, and R2 is independently selected from the group consisting of: linear or branched alkylene groups or substituted alkylene groups having from 1 to 18 carbon atoms, and arylene groups or substituted arylene groups having from 6 to 18 carbon atoms, wherein the molar ratio of nitrogen atoms on the polyamine to the acid groups on the ethylenically unsaturated acid is from 10:1 to 1:100, the composition is dissolved in a solvent and the solvent is selected from the group consisting of water, alcohol, ether derivatives of mono and poly glycols, and mixtures thereof, and the solvent constitutes 60-95 parts by weight of the total composition.
