Polyesteramide urethane resin has been synthesized from a nontraditional Malia Azedarach seed oil. The oil converted to N,N-bis (2-hydroxy ethyl) maleia azedrach oil fatty acid (HEMFA) by reacting with diethanol amine. HEMFA reacted with phthalic acid to obtained Malia Azedarach polyesteramide (MAPEA). The MAPEA treated with toluene-2,4-diisocyanate (TDI) in different ratios to synthesized polyesteramide urethane (MAPEAU). The optimum wt-% ratio of the TDI to the MAPEA is selected on the basis fluidity and film properties of the MAPEAU. The synthesized intermediates and final resin have been characterized by FT-IR, ¹HNMR spectroscopic analyses and by the measurement of physic-chemical properties like specific gravity, refractive index, acid value, iodine value, soponification value.
