Abstract

Se obtienen poliéter polialcoholes iniciados por amina, transparentes, por epoxidacion de una amina en presencia de un catalizador de hidroxido de metal alcalino. Una vez alcanzado el grado deseado de epoxidacion, se añade un ácido hidroxicarboxílico a la mezcla epoxidada en una cantidad suficiente para neutralizar cualquier posible hidroxido de metal alcalino remanente. Los polialcoholes producidos de esta manera son particularmente utiles para la produccion de espumas de poliuretano y poliisocianurato.
