Abstract
A amidoamine composition containing oligomeric amidoamine compounds having the structure:the average of x based on the amidoamine composition is at least 0.2, and Z is the residue of a polyoxyalkylene polyether polycarboxylic acid compound, and the amidoamine composition is the reaction product of primary polyamine compounds with polyoxyalkylene polyether polycarboxylic acid compounds at a corresponding equivalent weight ratio of at least 4.0:1 under oligomeric reaction conditions effective to increase the amine nitrogen equivalent weight of the amidoamine composition by at least 10% over the average acid equivalent weight of said polyoxyalkylene polyether polyacid composition. There is also provided glycidated amidoamine compositions used as epoxy functional surfactants, and the aqueous epoxy resin dispersions thereof, and the curable epoxy resin compositions thereof.
