Abstract
Abstract Bisester namely 1,1′-(1-methyl ethylidene) bis[4-{1-(1-imino-4-ethyl benzoate)-2-propa-nolyloxy}] benzene was synthesized by the reaction of epoxy resin (DGEBA) and 4-aminoethyl benzoate (4-AEB) using triethyl amine as catalyst. The synthesized bisester was reacted with three different aliphatic diamines viz; diethylene triamine (DETA), triethylene tetramine (TETA) and polyethylene amine (PEA) to obtained respective poly-amide resins (PAs) abbreviated as DGEBA-4-AEB: DETA, DGEBA-4-AEB: TETA and DGEBA-4-AEB : PEA respectively. The PAs synthesized were used as a curing agent for the difunctional epoxy resin (DGEBA) and trifunctional epoxy resin (TGPAP) in three different ratios. Using triethyl amine as a catalyst and PAs as a curing agent, DGEBA and TGPAP were polymerized on mild steel panels at 120[ddot]C for 1 hr. The coated panel thus obtained were tested for scratch hardness, flexibility, impact strength and chemical resistancy. It appears from the results for the epoxy resins, epoxy based poly...
