Abstract
Reaction products of polyamines with sulfonated oleic acid or sulfonated tall oil fatty acids are disclosed which give emulsions capable of producing cationic medium set mixing grade asphalt emulsions, as well as rapid set asphalt emulsions. Solventless asphalts as well as asphalts containing up to 15% by volume of a hydrocarbon oil can be used for emulsification.
