Abstract
La presente invención se refiere a copoliamida aromática, soluble en solventes orgánicos de poliamida, caracterizada porque contiene por lo menos 95 por ciento molar de las unidades estructurales repetitivos de las fórmulas: A, B, C, D y hasta 5 por ciento molar de las unidades estructurales E y/o F, derivadas de los ácidos dicarboxílicos (E') y/o de las diaminas aromáticas (F'), que contienen compuestos meta, en que los totales de partes molares de las unidades estructurales A+E y las partes molares B+C+D+F en esencia son iguales, Ar significa un radical aromático bivalente, cuyos compuestos de valencia están en posición para o en una posición coaxial o paralela comparable y que puede estar sustituído por dos radicales inertes, como alquilo inferior o halógeno, -r y -R' significan dos radicales de alquilo inferior o dos radicales de alcoxi inferior, diferentes entre sí, y las partes de los componentes diamínicos B, C y D se encuentran en la proporción respecto a la mezcla total de estos componentes diamínicos dentro de los siguientes límites: unidad estructural B: 30-55 por ciento molar; Unidad estructural C: 15-35 por ciento molar; unidad estructural D: 20-40 por ciento molar.
