Several new Schiff base derivative  were  prepared by   condensing various    aldehydes and ketones (aliphatic and aromatic ) with vinyl chloride copolymer hydrazine in presence of acid catalyst under reflux condition . All the compounds have been characterized on the basis of their softening points ,Viscosity and FT-IR spectral data

Some new cyclic imides are prepared by the reaction of ampicillin drug with different cyclic anhydrides as a first step to form amic acids for ampicillin drug. The second step includes the reaction of prepared amic acids with acetic anhydride and anhydrous sodium acetate with heating in THF as a solvent to give cyclic imide compounds. These compounds are identified by melting points, FT-IR, 1H-NMR, and biological activity
