    Patentansprüche
    1. Verfahren zum Herstellen eines Polyharnstoffpolymers, umfassend das Mischen eines Polyisocyanats, eines Polyepoxids und eines Polyamins und Erhitzen des Gemischs, wobei das Verfahren einen ersten Schritt des Mischens einer Polyharnstofformulierung, umfassend:
    (A) ein Polyisocyanat,
    (B) ein Polyepoxid,
    (C) ein Polyamin
    bei einer Temperatur von weniger als 13O0C unter Reaktionsbedingungen, die ausreichend sind, um ein Polyharnstoffpolymer zu bilden und einen zweiten Schritt des Nachhärtens des Polyharnstoffpolymers bei einer Temperatur von größer als 15O0C aufweist,
    worin das Polyisocyanat ausgewählt ist aus der Gruppe, bestehend aus TDI, IVIDI, PMDI, auf TDI basierenden flüssigen Polyisocyanaten mit Uretonimingruppen, auf MDI basierenden flüssigen Polyisocyanaten mit Uretonimingruppen, auf TDI basierenden flüssigen Polyisocyanaten mit Carbodiimidgruppen, auf MDI basierenden flüssigen Polyisocyanaten mit Carbodiimidgruppen, MDI-Präpolymeren und Gemischen davon.
    2. Verfahren nach Anspruch 1, worin das Mischen im ersten Schritt mittels einer Reaktionsspritzgußvorrichtung durchgeführt wird.
