| titleOfInvention | Bis(hydroxyphthalimide) and process for preparing the same, and process for preparing polyesterimide by the use thereof |
| abstract | The present invention provides a bis(hydroxyphthalimide) prepared by reacting 4-hydroxyphthalic anhydride and an organic diamine in the presence of an organic solvent under heating. The bis(hydroxyphthalimide) has two intramolecular imide rings and active hydrogens, and is thus polymerizable to form a variety of polycondensation products each having imide rings by condensation. The bis(hydroxyphthalimide) is also reacted with a dicarboxylic acid dihalide to form a polyesterimide, through condensation, which is excellent in transparency and heat resisting property. |
