ABSTRACT:
Reaction products of polyamines with certain polycarboxylic acid anhydrides are modified by reacting with formaldehyde and sodium sulfite or bisulfite, formaldehyde and phosphorus acid, haloalkane sulfonic acid salts, .gamma.-propane sultone, haloalkane phosphoric acid, acrylic acid, fumaric acid, maleic acid and haloalkanoic acids which give emulsions capable of producing medium set mixing grade asphalt emulsions, rapid set asphalt emulsions, and quick set slurry seal emulsions. Solventless asphalts as well as asphalts containing up to 15% by volume of a hydrocarbon oil can be used for emulsification.
