Abstract
La presente invención se refiere a un polímero de polieteruretano que contiene grupos isocianato y que tiene un contenido de NCO en el intervalo de 1,3 % a 1,9 % en peso y un contenido de diisocianato monomérico de no más de 0,5 % en peso, obtenido de la reacción de al menos un diisocianato aromático monomérico y un poliéter triol que tiene una funcionalidad de OH promedio en el intervalo de 2,2 a 2,6 y un índice de OH en el intervalo de 25 a 32 mg KOH/g en una relación NCO/OH de al menos 3/1, y posterior eliminación de una mayoría de los diisocianatos monoméricos por medio de un método de separación adecuado, y a composiciones de poliuretano de curado por humedad que tienen un contenido de diisocianato monomérico inferior al 0,1 % en peso, que comprenden dicho polímero. El polímero de la invención permite composiciones de poliuretano de curado por humedad muy estables al almacenamiento que pueden manipularse con seguridad incluso sin precauciones especiales de seguridad, tienen buena procesabilidad, tienen un tiempo abierto prolongado y curan rápidamente para brindar un material elástico de alta extensibilidad y elasticidad y que tienen alta resistencia, alta resistencia a la propagación del desgarro, buena flexibilidad en frío, buenas propiedades de unión y alta estabilidad, especialmente al calor y la radiación UV. Tales composiciones de poliuretano son especialmente adecuadas como adhesivos, selladores y revestimientos elásticos.
