Abstract

Procedimiento para la obtención in situ de dispersiones estables de productos de poliadición y policondensación, en caso dado conteniendo grupos iónicos, en compuestos que llevan grupos hidroxilo, como agentes de dispersión, caracterizado porque se hacen reaccionar a) poliisocianatos orgánicos con b) compuestos que llevan grupos amino primarios y/o secundarios y/o grupos hidroxilo primarios en c) compuestos que llevan como mínimo un grupo hidroxilo, llevando los compuestos que llevan como mínimo un grupo hidroxilo, llevando los compuestos c) grupo hidroxilo secundarios en el caso de que cuando compuestos b) se emplean aquellos con grupos hidroxilo primarios, en caso dado en presencia de más de un 4% en peso de agua, referido a la mezcla de reacción inclusive el agua, así como, en caso dado, bajo ulterior eliminación del agua en forma conocida, policondensándose simultáneamente con la reacción de poliadición de poliisocianato sustancias en el agente de dispersión c) que lleva grupos hidroxilo, capacitados para la formación de aminoplasto y/o fenoplasto.
