Abstract

Una composicion de poliol que tiene un peso molecular promedio en numero desde aproximadamente 1.000 hasta aproximadamente 3.000 Daltons esta constituida por (1) al menos 60% en peso de un polioxipropilen poliol de bajo monol con un peso molecular promedio en numero de desde aproximadamente 2.000 hasta 12.000 Da y un grado de insaturacion inferior o igual a 0,02 meq/g y (2) no mas de 40% en peso de un poliol con un peso molecular promedio en numero de desde aproximadamente 400 hasta aproximadamente 1.000 Da y un indice de polidispersidad superior a 1,1. Esta composicion de poliol se hace reaccionar con un diisocianato, un poliisocianato, un prepolimero terminado en isocianato o un cuasi-prepolimero terminado en isocianato para producir elastomeros de poliuretano con buenas propiedades fisicas y mecanicas. Pueden utilizarse cualquiera de los procedimientos conocidos para la produccion de los elastomeros de poliuretano, incluyendo los procesos "one-shot", para producir los elastomeros de acuerdo con la invencion.
