SYNTHESIS AND CHARACTERIZATION OF NEW POLYMALEAMIDES FROM N,N'-ETHANEDIANILINEBISISOMALEIMIDE WITH SOME AROMATIC DIAMINES

Five polymaleamides have been synthesised by the ring-opening poly add ition of N,N'-ethanedianilinebisisomaleimide (EBIMI) with aromatic dia mines (having methyl or methoxy ring substituents) at room temperature ; EBIMI was synthesised from N,N'-ethanedianilinebismaleamic acid. Inf rared, C-13 NMR, and UV-visible spectroscopies, inherent viscosity mea surements, thermogravimetry, differential scanning calorimetry and mas s spectrometry have been used to characterise these polymers.
