Abstract

Procedimiento para preparar una resina de aminoformaldehido, mediante reacción de un compuesto amino con formaldehído o paraformaldehido en fase líquido, caracterizado porque dichos compuestos se hacen reaccionar en presencia de un modificador reactivo para asegurar dicha fase líquida, comprendiendo el modificador una resina de amino-formaldehido capaz de reaccionar con otros monómeros y capaz de hacer que la mezcla de reactantes sea líquida a por lo menos la temperatura a la cual ha de realizarse la reacción.
