摘要：
Novel poly(imidosulfide) containing acidic pendent group has been synthesized by Michael addition reaction between dithiol and new synthesized bismalimide (BMI) monomer which was synthesized from 3,5-diaminobenzoic acid and 4-maleimidobenzoyl chloride. This new BMI that characterized completely with FT-IR, 1H-NMR, 13C-NMR spectroscopy and elemental analysis, copolymerized with glycol bis(mercaptoacetate) in N,N-dimethylacetamide in presence of p-toluenesulfonic acid as catalyst. The resulting polymer with carboxylic acid pendent group is soluble in polar solvents such as NMP, DMF, DMSO and DMAc. Reaction conditions were modified based on the reaction time, yield and viscosity. Synthesized poly(imidosulfide) was characterized by FT-IR, 1H-NMR, elemental analysis, thermogravimetric analysis (TGA) and X-ray diffraction (XRD) techniques. Acidic pendent group of the polymer has potential to form silver carboxylate metal salt. The synthesized poly(imidosulfide) silver complex reduced to form, new antibacterial bionanocomposite. The resulting nanocomposite was characterized by FT-IR, UV/Vis, XRD, TGA, FE-SEM/EDX and TEM. Also antibacterial properties and bacterial degradation of nanocomposite and polymer were investigated.
