Abstract

La presente invencion se refiere a un nuevo procedimiento para la preparacion de masas de moldeo masivas de poliuretano, que pueden presentar espesores de pared delgados a causa de la alta autorrigidez, asi como una geometria compleja. Los cuerpos de moldeo de poliuretano segun la invencion se pueden preparar mediante reaccion de poliisocianatos seleccionados con compuestos con grupos reactivos frente a grupos isocianato seleccionados segun el procedimiento de fundicion, es decir, con una tecnologia de procesamiento sencilla y economica.
