Abstract

Procedimiento para la obtención in situ de dispersiones acuosas de productos de poliadicion de poliisocianato en compuestos conteniendo grupo hidroxilo como agente de dispersión, por reacción de 1. poliisocianatos orgánicos con 2) compuestos conteniendo grupos amino primarios y/o secundarios y/o grupos hidroxilo primarios, y/o amoniaco, así como en caso dado formaldehído, en 3) compuestos conteniendo como mínimo un grupo hidroxilo, donde los compuestos 3 poseen grupos hidroxilo secundarios en caso de que como compuestos 2 se empleen aquellos con grupos hidroxilo primarios, caracterizado porque les componentes de reacción se hacer reaccionar en presencia de mas de un 4 % en peso de agua, referido a la mezcla de reacción inclusive el agua y, en caso dado, a continuación se retira el agua y, en caso dado, a continuación se retira el agua en forma en si conocida.
