A brief report on novel polyazobenzoxazinones
Polybenzoxazinones were synthesized by solution polycondensation from five different aromatic diacidchlorides and 3,3′‐diaminoazobenzene‐4,4′‐dicarboxylic acid through a polyamic acid precursor which was further cyclodehydrated to polybenzoxazinones. The amic acid and the benzoxazinones were obtaine...

| Zusammenfassung: | Polybenzoxazinones were synthesized by solution polycondensation from five different aromatic diacidchlorides and 3,3′‐diaminoazobenzene‐4,4′‐dicarboxylic acid through a polyamic acid precursor which was further cyclodehydrated to polybenzoxazinones. The amic acid and the benzoxazinones were obtained in 85–93% and 56–63% yield, respectively. The polymers were characterized by physical and thermal analysis. |
