Abstract

Procedimiento para la obtención de poliisocianatos conteniendo grupos biuret y/o poliuret superiores, caracterizado porque se hacen reaccionar diaminas de fórmula R1-NH-R2-NH R3 con cantidades en exceso de diisocianatos orgánicos de fórmula R4(NCO)2 donde R1 y R3 significan restos iguales o diferentes y son restos hidrocarburo alifáticos con 1 hasta 20 átomos de carbono, que también enlazados entre si, bajo inclusión de un armazón básico de diamina, pueden formar un anillo de 5 ó de 6 miembros, o restos hidrocarburo cicloalifáticos con 4 hasta 15 átomos de carbono y R2 y R4 significan restos iguales o diferentes y son restos hidrocarburo alifáticos.
