Description
wohingegen die Amidbildung bei einer etwas höheren Temperatur erfolgt, wenn sich die Reaktionsteilnehmer bei etwa 200 bis 300 0C befinden. Nach dem Ende der Umsetzung ist praktisch die Gesamtheit der Lösungsmittel destillativ entfernt, und es hinterbleibt eine polymere Amidimidschmelze mit einer inhärenten Viskosität, IV, von etwa 0,1 bis 0,3. Wie bereits erwähnt, sollen die Alkanole, wenn solche mit mehr als 5 Kohlenstoffatomen verwendet werden, rasch aus der Reaktionsmischung entfernt werden, um einen Kettenabbruch durch Veresterung des einwertigen Alkohols zu vermeiden. Eine rasche Entfernung der höheren Alkanole kann durch Vakuumdestillation unterstützt werden.
840 kg/cm (12 000 psi) und die Platten zeigen nach 24-stündigem Erwärmen auf 230 C und anschließendem 24-stündigem Erwärmen auf 260 C weder Gasbildung noch Verformung.
