Abstract

Un procedimiento para hacer un polímero partiendo de una amida cíclica que contenga más de seis átomos de carbono anular, que comprende las etapas de suministrar continuamente a una vasija de reacción un monómero de amida cíclica, un catalizador de polimerización rápida y una pequeña cantidad de un interruptor de cadena escogido de entre el grupo consistente en carboxi-amidas en las que el grupo amídico no forme parte integrante de una extructura de anillo, someter la mezcla a condiciones de polimerización, y retirar continuamente de dicha vasija de reacción una poliamida.
