This study includs the synthesis of some new Amic acid and Imides,starting from the esters [S1] of Terephthalic acid which then converted toits hydrazide [S2] then to amic acid derivatives [S3-S7] and finally withimides [S8-S12]. Preparing of ester [S1] by usual esterification ofterephthalic acid with absolute ethanol in acidic medium, then hasconverted to its hydrazide [S2] by reacting it with hydrazine hydrate. Theamic acid derivatives [S3-S7] have been synthesized by the reaction ofhydrazide [S2] with anhydrides (2,3-dimethyl malic anhydride, 3-nitrophthalic anhydride, hexahydro phthalic an

The reaction of 2-hydroxyethyl methacrylate with 3-nitrophthalic anhydride catalyzed with triethylamine results in the 3 : 1 mixture of two possible monoesters, the more populated one being that with the ester group in ortho position to the nitro group. The isomers were identified and quantified by 1H and 13C 1D and 2D techniques including APT, INEPT, superselective long-range (SSLR) INEPT, SSLR HHCR, COSY, NOESY, HETCOR and COLOC.

Polyetherimides (PEIs) are a class of structural polymers with the most successful combination of such essential properties for practical applications as high heat resistance, thermal stability, ultimate tensile strength, elastic modulus, good dielectric properties, and high chemical and radiation resistance. However, along with these advantages, PEIs are compounds with high softening and melting points, which complicates their processing into products.
