NOVEL CONDENSATION FUNCTIONAL POLYMERS HAVING HIGHLY BASIC GROUPS

The cardo polyimides and polyamides having highly nucleophilic quinucl idine groups have been synthesized with the usage of 3,3-bis(4-aminoph enyl)quinuclidine as amine monomer. The latter has been obtained by th e condensation of quinuclidone-3 with aniline. The characterization of such amine, including quaternization reaction, is performed. Polyimid es have been derived from this monomer and various tetracarboxylic dia nhydrides by one- and two-step polycyclization. Quinuclidine moieties enhance the one-step polyimide formulation leading to high molecular p olymers including corresponding poly-1,4,5,8-naphthoyleneimides even w ithout any added catalyst. It is stated that polyamic acid formation i s hindered by the side tertiary-amine-COOH salt formation. The latter reaction is eliminated by the preliminary quaternization of amine mono mer. The high molecular polyamides have been prepared by low-temperatu re solution polycondensation of cited monomer and diacid chlorides. Th e obtained polymers are characterized by high thermal properties, solu bility in organic solvents and represent the quite efficient catalysts for polyamic acid imidation in homo- and heterogeneous systems.
