Abstract

Procedimiento para la obtención de amino- y/o fenoplastos, según el cual se obtiene en una primera extrusora 14 una solución de precondensado, caracterizado porque se hace llegar la solución de precondensado (16) con adición de aditivos de forma continua a una segunda extrusora (20) con rellenado parcial en la zona de entrada (E) y en la zona de desgasificación (G), se desgasifica en la segunda extrusora (20) y se moldea a continuación para dar un producto final.
