Abstract

Procedimiento para la obtención de un aminoplasto modificado caracterizado porque se condensan formadores de aminoplasto y compuestos carbonílicos y en caso dado modificadores hasta una dilubilidad con agua limitada o ilimitada y antes, durante o tras la condensación se adiciona como modificador un producto de condensación de epsilon-caprolactama, formaldehído y formamida en una cantidad tal que el aminoplasto terminado, presenta un contenido en el mismo, referido al contenido de material sólido de la resina terminada, comprendido entre 0,5 y 40% en peso.
