Abstract

La presente invención se refiere a un método para la preparación de una composición polimérica termoendurecible de poliisocianurato modificada con poliuretano rígido moldeado por transferencia o por vaciado o fundido, caracterizado por llevar desde una cámara de mezclado, dentro de la cavidad de un molde de la configuración deseada, que puede ser comprimido, para reaccionar a temperaturas de desde aproximadamente la temperatura ambiente hasta aproximadamente 140 grados C, una mezcla de reacción de un di- o poliisocianato orgánico, desde aproximadamente 2 hasta aproximadamente 50 partes por peso de un carbonato de alquileno cíclico, y desde aproximadamente 2 hasta aproximadamente 50 partes por peso de un poliol de poliéter, basado en 100 partes de la composición de isocianato-carbonato-poliol, en la presencia de un aducto soluble de una amina terciaria y un carbonato de alquileno cíclico como catalizador a una concentración de desde aproximadamente 0.005 hasta aproximadamente 5.0 por ciento por peso basado en la composición total.
