摘要: Aromatic poly(ether imide)s were synthesized using two diamines containing one or nitrile groups and ether linkages, with dianhydrides exhibiting different degrees of flexibility. The effect inserted into polymer chains, was correlated their physical properties. polymers have a very good solubility high thermal stability. Poly(ether had the initial decomposition temperature in range 400–520°C glass transition temperatures domain 169–232°C, depending on rigidity chain. electrical properties molecular relaxations evaluated, taking account presence polar group.
