Abstract

Procedimiento para la obtención de poliisocianatos de alofanato, conteniendo como mínimo tres grupos isocianato, por reacción de compuestos que lleven grupos hidroxilo, con cantidades en exceso de poliisocianatos orgánicos, libres de grupos alofanato, caracterizado porque como compuestos que llevan grupos hidroxilo se hacen reaccionar aquellos de fórmula **(Fórmula)** donde R1 y R2 son restos iguales o diferentes y significan hidrógeno, restos hidroxialquilo, alquilo o cicloalquilo, con la limitación de que como mínimo uno de los restos R1 y R2 está por hidrógeno o un grupo hidroxialquilo y R3, R4, R5 y R6, son restos iguales o diferentes, y significan hidrógeno, restos alquilo o hidroxialquilo, y donde los restos R3 y R5 junto con los dos átomos de carbono del armazón básico también pueden formar un anillo cicloalifático.
