- Abstract
In the present study, new homo and Copolymers maleimide were synthesized based on the polymerization of maleimide compound which synthesized from sulfa drugs. The first step including Azo coupling reaction of Dapsone with pnitroaniline to synthesized compound (A). The compound (A) was converted to Amic acid, compound (B) via reaction with maleic anhydride. The compound (B) when react with acetic anhydride in the presence of sodium acetate it will be give maleimide compound (C). The Homopolymaleimide polymer (D) can be obtained by heated maleimide compound (C) with AINB initiator. While maleimide compound (C) was converted to copolymer maleimide when react with acryl amide in the presence of AINB initiator using DMF as a solvent. All the synthesized compounds have been characterized by TLC, FT-IR, ¹H.NMR Spectroscopy and 13C NMR spectroscopy and study the thermal properties.
