ABSTRACT:
Novel amphoteric emulsifiers are disclosed for solventless and solvent containing mixing grade, oil-in-water anionic and cationic bituminous emulsions, which emulsifiers are the modified reaction products of polyamines with certain polycarboxylic acids and sulfonated carboxylic acids. Modifications are carried out by reacting the nitrogen-containing intermediate with formaldehyde and sodium sulfite or bisulfite, chloroalkane sulfonic acid salts, .gamma.-propane sultone, chloroalkane phosphonic acids, acrylic acid, fumaric acid, maleic acid and chloroethanoic acid.
