Abstract

Se trata de la preparacion de poliéterespolioles adecuados para su uso en la preparacion de espumas de poliuretano rígidas, mediante un procedimiento queutiliza catalizadores de imidazol. Los catalizadores de imidazol no pierden la reactividad a temperaturas elevadas y pueden utilizarse a temperaturas mayorespara preparar polioles y de ese modo reducir el tiempo de resistencia y el consumo de energía en los procedimientos de produccion de polioles. Dichoprocedimiento comprende preparar poliéterpolioles mezclando un iniciador de oxido de alquileno en presencia de catalizador de imidazol en condiciones dealcoxilacion de temperatura suficiente para preparar poliéterpolioles con la condicion que cuando se utiliza un iniciador aminoaromático ,la alcoxilacion serealiza a una temperatura mayor a los 125s.
