| Research Abstract |
Rigid-rod aromatic polymers are expected to possess many excellent properties. However, many of them do not exhibit processability such as solubility and fusibility because of their rigid-rod structure and they had been given up to use as materials. We examined the reaction-induced phase separation during polymerization in order to overcome the antagonistic problem between the high performance and the less processability. The network structures of polyester, polyimides, polybenzimidazoles and poly(ether ketone) were successfully prepared. And further, helical ribbon of poly(ester-imide) and nanofibers of polyazomethine and polyimidazopyrrolone which is a perfect ladder polymer were also obtained.
