Novel method for preparation of polybenzimidazole under mild condition |
| abstract |
The present invention relates to a preparation method of polybenzimidazole comprising the following steps of: I) mixing an aromatic tetraamine monomer and a bisulfite adduct of aromatic dialdehyde as reactants for 1-2 hours without adding a solvent; II) adding an organic solvent to the reactants, and conducting condensation polymerization of the resultant product at 150-200C for 15-24 hours to obtain a polymer solution; and III) obtaining polybenzimidazole powder by passing the polymer solution through a series of processes of precipitating in deionized water, cleaning, and drying. |
