AbstractThe study includes the preparation of the acidic monomer, benzidine bis maleimic BMA, and the monomer was investigated by IR technique. Copolymerization of the acidic monomer benzidine bis maleamic BMA with styrene, methyl methacrylate in was accomplished DMF was studies. The copolymers were investigated by their colors, solubility and IR technique.
The relative monomer reactivity ratios in prepared copolymers were studied and azeotropic copolymerizations was not found at all monomer concentrations and the PBMA ratio was higher in copolymer in all cases. Thermal studies of the copolymers by using TGA, IGA technique, Indicate that the polybismaleimide possess higher thermal stability in comparison with other polymaleimides .As well as, thermal stability in was increased directly with increasing the molar ratios of acidic monomer benzidine bismaleamic acid BMA. The reactivity ratios study appeared that the type of copolymerization prefers to be alternate copolymer.
