Notes:
A series of novel polyphenylquinoxalines containing naphthalimide structures in the chain were prepared by reacting 3,3′-diaminobenzidine, 3,3′,4,4′-tetraaminodiphenyl ether and 3,3′,4,4′-tetraaminodiphenyl sulfone with the two new monomers of N,N′-bis(4-benzoylcarbonylphenyl)-4,4′-(1,3-phenylenedioxy)-di-1,8-naphthalenedicarboximide (3a) and N,N′-bis(4-benzoylcarbonylphenyl)-4,4′-[isopropylidenebis(1,4-phenyleneoxy)]-di-1,8-naphthalenedicarboximide (3b). The obtained polymers exhibit high decomposition temperatures, their Tg values being, however, below 300°C. Their solubility in common solvents, e.g. chloroform, is excellent, but their molecular weight is low. Higher molecular weight products were obtained by copolymerization of 3a, b with N,N′-bis(4-benzoylcarbonylphenyl)-1,8 : 4,5-naphthalenetetracarboxdiimide (3c) yielding films and fibers with good mechanical properties.
