Abstract The condensation products of alkyl-substituted aromatic dicarboxylic acid and polyoxyalkylene polyamines were synthesized and used as epoxy curing agents. The novel amidoamines, prepared from t-butyl isophthalic acid (t-BuIPA) and polyoxyethylene diamines such as Jeffamine(R) EDR-148 and 192, exhibited fast cnring and good flexibility. Comparisons with other amidoamines derived from isophthalic and Dimer acid, and amines including Jeffamine(R) D-230, were made. The functionalities of alkyl and less hindered amines in the amidoamine structures affect the epoxy curing rate and material flexibility.
