Wholly aromatic polyamide from N,N'-bis (4-amino phenyl)-isophthalamide |
摘要 |
New wholly aromatic polyamides are provided. This polymers are prepared by a mixture of N,N'-bis(4-aminophenyl)-isophthalamide and p-phenylenediamine in a tertiary amide solvent containing an alkali metal salt such as LiCl and a tertiary amine as an acid acceptor. The polymers are easily dry-jet spun to form a fiber and cast to form a film. The fiber and film so obtained have ultrahigh tenacity, elasticity and elongation.
