| titleOfInvention | Production of aromatic polyamide copolymer |
| abstract | PURPOSE: To easily obtain the titled copolymer having high glass transition temperature, excellent heat-resistance and high strength and free from aliphatic chain in the main chain, on an industrial scale, by reacting a specific aromatic diisocyanate with an aromatic dicarboxylic acid in a solvent under heating. n CONSTITUTION: An aromatic diisocyanate of formula I [Ar is -C 6 H 4 -X-C 6 H 4 -(X is CH 2 or O) or tolylene] (e.g. diphenylmethane-4,4'-diisocyanate,2,6-tolylene diisocyanate, etc.) is made to react with aromatic dicarboxylic acids of formula II (0W90mol%) and formula III (100W10mol%) [X' is -CH 2 -,-CH 2 CH 2 -, -O-, -S-, -SO 2 -, -C(CH 3 ) 2 - or -CO-; R is H, 1W5C alkyl, methoxy or ethoxyl (e.g. isophthalic acid) in one or more solvents selected from tetramethylene sulfone and diphenyl sulfone preferably by heating at 160W230°C. n COPYRIGHT: (C)1988,JPO&Japio |
