Polymers derived from chloromaleic anhydride as detergent builders
Abstract
Abstract DETERGENT COMPOSITIONS ARE DESCRIBED COMPRISING A DETERGENT SURFACTANT AND A WATER-SOLUBLE SALT OF A POLYMERIC BUILDER OF THE FORMULA (X(1-M-N)YMZN)P WHEREIN M AND N ARE POSITIVE NUMBERS WHOSE SUM IS LESS THAN UNITY, P IS AN INTEGER THE LOWER LIMIT OF WHICH IS 3 AND THE UPPER LIMIT OF WHICH IS DETERMINED BY THE SOLUBILITY OF THE SALT IN AN AQUEOUS SYSTEM, X IS DERIVED FROM THE MONOMER MONOCHLOROMALEIC ACID, Y IS DERIVED FROM THE MONOMER MALEIC ACID ANS Z IS DERIVED FROM A MONOETHYLENICALLY UNSATURATED MONOMER CONTAINING 1 TO 3 SUBSTITUENTS SELECTED FROM THE CLASS CONSISTING OF CARBOXY, LOWER CARBOXYALKYL, LOWER ALKYL, LOWER CHLOROALKTL, HYDROXY, NON-GEM. DIHYDROXY, LOWER ALIPHATIC ACYLOXY, CHLORO AND LOWER ALKOXY, IT BEING PROVIDED THAT SOME OF THE CARBOXY GROUPS IN THE POLYMER CAN BE ESTERFIED WITH A LOWER ALIPHATIC RADICAL.
