| titleOfInvention | Production of wholly aromatic polyamide carrying pendant primary amino group |
| abstract | PURPOSE: To obtain in an industrially stable manner the titled polyamide suitable for, e.g., adhesivity enhancer for aramid fiber, by polymerization between a substituted nitro group-carrying aromatic dicarboxylic acid dichloride and aromatic diamine followed by reduction of the nitro group. n CONSTITUTION: First, a pendant nitro group-carrying wholly aromatic polyamide is prepared by low-temperature polymerization, in the presence of, e.g., an acid acceptor (e.g., alkali metal carbonate) and water, between (A) a 6W22C (constituted by 1W3 aromatic ring) aromatic dicarboxylic acid dichloride carrying 1W2 substituted nitro group per molecule (e.g., 2-nitroterephthaloyl chloride) and (B) an aromatic diamine (e.g., p-phenylenediamine). The objective polyamide can be obtained by reduction, using a reducing agent (e.g., sodium hydrosulfite), in a medium such as water, of said aromatic polyamide. If desired, the component A may be incorporated with 0W50mol% of a nitro group-free analogue thereof. n COPYRIGHT: (C)1987,JPO&Japio |
