Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Chemical Engineering Summary: This work presents copolymer N,N{u2032}-bissulphinyl-m-benzenediamine-p-phenylenediamine (SMBD-PPD) is synthesized by using michael addition on reacting of N,N{u2032}-bissulphinyl-m-benzenediamine (SMBD) with p-phenylenediamine at 180-200 {u00B0}C and characterized with various physical and chemical techniques. The number average of molecular weight of SMBD-PPD copolymer is estimated using 1H{u2013}NMR spectroscopy to be about 3160 g/mole. The absorption properties of SMBD-PPD copolymer showed two main absorption peaks at n=247 and 303 nm in methanol solution and at n=238 and 299 nm in ethanol. The energy gap is found in the range of 2.1-2.5 eV. SMBD-PPD copolymer showed emission characteristics. The emission spectra appeared at n=460 and 490 nm. The dc and ac electrical conductivities and dielectrical properties at different temperature and frequencies are investigated. The dominant conduction mechanism for ac conductivity in SMBD-PPD copolymer is found to be quantum mechanical tunneling. From these results, SMBD-PPD copolymer can be used for several applications such as polymer solar cell, laser and light emitting diodes
