A process for making a dispersion in aqueous media, said dispersion comprising a hydrolysis resistant cationic polyamide polymer having cationic dispersing groups and comprising one or more polyamide segments, wherein said cationic species are tertiary amines salted with a volatile organic or inorganic acid and/or quaternized tertiary amines incorporated into the polyamide segments during the synthesis of the polyamide, said process comprising the steps of a) providing a polyamide prepolymer comprising i) at least one primary or secondary amine terminal group, with the other terminus or termini if the polymer is branched being another species, and ii) at least 1 milliequivalent of said tertiary amine in the form of a salt, a quaternized tertiary amine, or combinations thereof; b) dispersing said polyamide prepolymer in water, wherein (i) carbon dioxide is employed to help plasticize said prepolymer, and (ii) at least 0.1 moles of said carbon dioxide is present per mole of terminal amine groups in the prepolymer, said carbon dioxide being added either to the prepolymer, to the water phase or to both. said cationic species are tertiary amines salted with a volatile organic or inorganic acid and/or quaternized tertiary amines incorporated into the polyamide segments during the synthesis of the polyamide, said process comprising the steps of a) providing a polyamide prepolymer comprising i) at least one primary or secondary amine terminal group, with the other terminus or termini if the polymer is branched being another species, and ii) at least 1 milliequivalent of said tertiary amine in the form of a salt, a quaternized tertiary amine, or combinations thereof; b) dispersing said polyamide prepolymer in water, wherein (i) carbon dioxide is employed to help plasticize said prepolymer, and (ii) at least 0.1 moles of said carbon dioxide is present per mole of terminal amine groups in the prepolymer, said carbon dioxide being added either to the prepolymer, to the water phase or to both. a) providing a polyamide prepolymer comprising i) at least one primary or secondary amine terminal group, with the other terminus or termini if the polymer is branched being another species, and ii) at least 1 milliequivalent of said tertiary amine in the form of a salt, a quaternized tertiary amine, or combinations thereof; i) at least one primary or secondary amine terminal group, with the other terminus or termini if the polymer is branched being another species, and ii) at least 1 milliequivalent of said tertiary amine in the form of a salt, a quaternized tertiary amine, or combinations thereof; b) dispersing said polyamide prepolymer in water, wherein (i) carbon dioxide is employed to help plasticize said prepolymer, and (ii) at least 0.1 moles of said carbon dioxide is present per mole of terminal amine groups in the prepolymer, said carbon dioxide being added either to the prepolymer, to the water phase or to both. (i) carbon dioxide is employed to help plasticize said prepolymer, and (ii) at least 0.1 moles of said carbon dioxide is present per mole of terminal amine groups in the prepolymer, said carbon dioxide being added either to the prepolymer, to the water phase or to both.
