Abstract
Description
- 1. Bekannte Reaktion Epoxidharz/Polycarbonsäureanhydrid (Komponente B),
- 2. Beschleunigung der Reaktion 1) durch die Komponente C, z. B. Harnstoff,
- 3. Reaktion der Komponente B mit Komponente C "in-situ" unter Bildung von Ureiden bzw. N-Acylharnstoffen bzw. Ureido-Derivaten mit mindestens einer Carboxylgruppe im Molekül,
- 4. Reaktion der Umsetzungsprodukte von 3) durch NH- und/oder NH2-Gruppen mit Epoxidharz.
Ansatz a) wird unter Rühren bei 115°C (Richtwert 90 min) zu einem Endprodukt mit einem Schmelzpunkt von etwa 40°C umgesetzt.
Ansatz b) wird unter Rühren bei 130°C (Richtwert 45 min) zu einem Endprodukt mit einem Schmelzpunkt von etwa 40°C umgesetzt.
Ansatz c) wird unter Rühren bei 150°C (Richtwert 40 min) zu einem Endprodukt mit einem Schmelzpunkt von etwa 50°C umgesetzt.
