Abstract
Procedimiento de obtención de materiales de poliuretano, útiles para la toma de moldes, particularmente en odontología, caracterizado porque comprende hacer reaccionar, en proporciones estequiometricas, 1 mol de un dihidroxi compuesto de peso molecular entre 300 y 10.000, con 2 moles de un diisocianato y con 2 moles de un monohidroxi-compuesto insaturado, preferiblemente derivados de ácido acrílico y/o metacrílico que llevan grupos hidroxilo, a temperatura ambiente, y en presencia de 0,001 a 10% en peso de un catalizador, calculado sobre la cantidad total de masa de reacción.
