Abstract

La presente invencion tiene por objeto una composicion que comprende: cuando menos un poliisocianato subyacente o no subyacente, bajo la forma de una emulsion acuosa cuyo tamaño promedio está comprendido entre 0.1 y 10 micras y de preferencia inferior a 2 y superior a 0.2 micras; cuando menos un polímero polihidroxilado, ventajosamente un poliol, bajo forma de una segunda dispersion acuosa cuyo tamaño promedio está comprendido entre 10 y 200 nanometros. Esta composicion está caracterizada porque la cantidad de polímero polihidroxilado, ventajosamente de poliol de la mezcla, se selecciona de manera correspondiente con la limitacion siguiente: el porcentaje de contenido de polímero polihidroxilado, ventajosamente de poliol, expresado en por ciento másico, es cuando menos igual a 5/6R-20, ventajosamente cuando menos igual a 5/6R-18, de preferencia a 5/6R-16; con R igual a la relacion entre tamaño promedio (d50) de la emulsion y aquella de la dispersion de polímero polihidroxilado, ventajosamente de poliol. Se aplica a la síntesis orgánica.
