Soluble rigid rod-like polyimides and polyamides containing curable pendent groups

摘要: Abstract Soluble rod-like aromatic polyimides and polyamides containing curable pendent groups were synthesized. The (PIEANs) (PAEANs) enaminonitrile showed good thermal stability, underwent curing reactions without the emission of volatile by-products above 300 °C to stable materials which not soluble in any organic solvents. However, (PIEONs) (PAEONs) enoxynitrile started decompose around 300 °C, because instability groups. PAEONs 420 °C spite initial decomposition, but PIEONs exhibited only degradation process. Thermal analyses these polymers corresponding model compounds revealed that proceeded via intermolecular crosslinking as well intramolecular cyclization, while groups, known undergo self-curing reaction, could be cured by itself, a reactive amine group was essential for
