Abstract
Reaction products of polyamines with epoxidized vegetable oils or epoxidized fatty esters 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 12% by volume of a hydrocarbon oil can be used for emulsification. Emulsions prepared with these condensation products behave similarly to emulsions prepared with condensation products of polyamines and tall oil derived C.sub.21 -dicarboxylic acid, C.sub.22 -tricarboxylic acid or sulfonated tall oil fatty acids.
