Abstract

Procedimiento para la preparación de polioles modificados, caracterizado porque en su realización se hacen reaccionar dioles con un peso equivalente comprendido entre 30 y 150, con poliisocianatos con un peso equivalente comprendido entre 50 y 200, conduciéndose la reacción en forma tal que se mantiene entre ambos componentes una relación ponderal diol/isocianato comprendida entre 10 y 1, de preferencia entre 5 y 1,6 y una relación equivalente OH/NCO comprendida entre 3 y 50, de preferencia entre 4 y 10.
