A COMPOSITION CONTAINING IN AQUEOUS DISPERSION A SOLID ETHYLENE POLYMER AND A SALT OF THE CLASS CONSISTING OF AMMONIUM AND WATER-SOLUBLE BASIC AMINE SALTS OF AN N-MONOALKYL SUBSTITUTED POLYMERIC AMIC OF AN INTERPOLYMER OF A POLYMERIZABLE ORGANIC COMPOUND CONTAINING AN ETHYLENIC DOUBLE BOND AS THE SOLE ALIPHATIC CARBON-TOCARBON UNSATURATION WITH A BUTANEDIOIC ACID ANHYDRIDE, THE RECURRING TWO NON-OXO CARBONYL GROUPS IN SAID POLYMERIC AMIC ACID BEING ATTACHED DIRECTLY TO ADJACENT CARBON ATOMS OF THE POLYMERIC CHAIN WHICH CONTAINS STRUCTURAL UNITS IN WHICH THE AMIDE NITROGEN ATOM HAS ATTACHED THERETO HYDROGEN AND A LON-CHAIN MONOALKYL SUBSTITUENT OF A LEAST SEVEN CARBON ATOMS, THE BASIC AMINES OF SAID SALTS BEING THOSE HAVING AN IONIZATION CONSTANT VALUE GREATER THAN 1X10**-6 WHEN MEASURED AT 25*C. AND BEING SOLUBLE TO THE EXTENT OF AT LEAST FIVE PARTS PER 100 PARTS OF WATER AT 25*C.
