Abstract

Procedimiento para la obtención de un agente para el encolado de papel, compuesto de un preparado acuoso de amidas de ácido graso básicas cuaternizadas, caracterizado porque se emplean amidas en promedio de básicas de a) un ácido graso o una mezcla de ácidos grasos teniendo puntos de fusión superiores a 30ºC y b) una o más aminas correspondientes a la fórmula general **(Fórmula)** y/o las mezclas industriales de las mismas, donde R y R'' son iguales o diferentes y significan un resto alquileno con 2 ó 3 átomos de carbono y n tiene un valor de 1 - 6, y la mezcla industrial de las aminas pueden contener hasta un 80% en peso de sustancias acompañantes compuestas esencialmente de aminas ciclicas y/o ramificadas con aproximadamente al mismo márgen de punto de ebullición industrial, las amidas se cuaternizan con 0,5 hasta 2 equivalentes de apiclorohidrina (referido a los grupos amino en la amina básica) en presencia de agua y entonces, en caso dado, se diluye con más agua a una concentración de sólidos deseada.
