Patent number: 6767885Abstract: A hydrophilic polymer with improved biodegradability and particular usefulness in detergent compositions contains units derived by polymerization from at least one monomers A bearing a carboxylic acid function or an equivalent function, units derived by polymerization from at least one monomers B bearing an electron-rich group or a function capable of introducing an electron-rich group into the main chain, and, optionally, units derived by polymerization from at least one monomers C which is copolymerizable with A and B, but is different from A and B. Examples of suitable monomers as monomers A include maleic anhydride, acrylic acid, methacrylic acid, itaconic acid, fumaric acid and maleic acid, and the salts thereof. Examples of suitable monomers as monomers B include butadiene, isoprene, chloroprene, dimethylbutadiene, cyclohexadiene, butadienecarboxylic acid, butadienedicarboxylic acid, acetylene, acetylenecarboxylic acid and acetylenedicarboxylic acid.Type: GrantFiled: June 1, 2001Date of Patent: July 27, 2004Assignee: AtofinaInventors: Christian Gancet, Rosangela Pirri, Bernard Boutevin, Cédric Loubat, Jean Lepetit
