Abstract

Procedimiento para preparar resinas de melamina-formaldehído parcialmente eterificadas, caracterizado porque la melamina y el formaldehído, en una relación molar de 1: (1,25 hasta 1), se condensan hasta una diluibilidad con agua de 1: (0,5 hasta 2,5), en presencia de un glicolmonoéter de fórmula general R(OCH2CH2)nOH (I) donde R significa alquilo con 1 a 4 átomos C y n un número entero de 1 a 5, y en presencia de un electrolito que permite ajustar un valor pH de aproximadamente neutro hasta débilmente alcalino.
