Abstract
Procedimiento para preparar poliamidas a partir de los correspondientes monómeros yio prepolímeros, que comprende los pasos de (a) transformar los monómeros y/o prepolímeros y eventualmente otros componentes en condiciones de reacción formadoras de poliamida, con lo cual se genera poliamida, (b) tratar la poliamida contenida en el paso (a) en una amasadora a una temperatura superior a la temperatura de fusión de la poliamida, (c) continuar elaborando la poliamidas del paso (b) para dar granulados, hojas delgadas, fibras o cuerpos moldeados, de preferencia granulando la poliamida, (d) extraer de la poliamida por lo menos una parte del monómero no transformado y eventualmente oligómeros que se hayan generado, así como eventualmente otros componentes, y/o secar la poliamida.Process for preparing polyamides from the corresponding monomers and or prepolymers, comprising the steps of (a) transforming the monomers and / or prepolymers and possibly other components into polyamide-forming reaction conditions, whereby polyamide is generated, (b) treat the polyamide contained in step (a) in a kneader at a temperature higher than the melting temperature of the polyamide, (c) continue making the polyamides of step (b) to give granules, thin sheets, fibers or molded bodies, preferably by granulating the polyamide, (d) extracting from the polyamide at least a part of the non-transformed monomer and possibly oligomers that have been generated, as well as possibly other components, and / or drying the polyamide.
