Abstract

Un procedimiento de preparación de un uretano que consiste esencialmente en efectuar la reacción de polimerización entre un poliol y un poliisocianato en presencia de N,N,N',N',N''-pentametildipropilentriamina, siendo utilizada esta triamina en una proporción comprendida entre 0,02 y 4,0 % del peso de dicho poliol.
