| titleOfInvention | Preparation of aromatic polyamide |
| abstract | PURPOSE: To obtain the title polyamide useful as film materials, etc. in good operating efficiency, by reacting an aromatic diamine and an aromatic dicarboxylic dihalide in a nitrogen-containing organic solvent having a specific amount of 1,3-dimethyl-2-imidazolidinone. n CONSTITUTION: 30W80Vol% of 1,3-dimethyl-2-imidazolidinone is added to a nitrogen-containing organic solvent, e.g., N,N-dimethylacetamide, N-methyl-2-pyrrolidone. In the resulting solvent, an aromatic diamine, e.g., p-phenylenediamine, methyl p-phenylenediamine, 2,6-diaminonaphthylene, benzidine-sulfonic acid is reacted with an aromatic dicarboxylic dihalide, e.g., terephthaloyl dichloride, tetrachloroterephthaloyl dichloride at a temperature range of not higher than 60°C, preferably about 20W50°C under stirring and the reaction product is neutralized to give the desired polyamide. n COPYRIGHT: (C)1980,JPO&Japio |
