Claims (3)

1. Vorrichtung zur kontinuierlichen und kurzzeitigen Herstellung von feinen und gleichmäßigen Polymerdispersionen aus Pulver in ihrem flüssigem Lösungsmittel, dadurch gekennzeichnet, daß sie umfaßt :
eine Turbine (2), die von einem Motor (5) angetrieben wird und auf der nur zwei Schaufelreihen (3 und 8) angebracht sind, die den Rücklauf des Produkts zum Zentrum der Turbine verhindern, wobei eine Reihe (3) konzentrisch zur Mitte liegt und die andere Reihe (8) konzentrisch zur Reihe (3) am äußeren Abschnitt der Turbine (2) angebracht ist, wobei der Materialfluß auf freie und kontinuierliche Art und Weise erfolgt, ohne auf Hindernisse zu treffen, mit Ausnahme der Schaufeln (3 und 8),
eine einzelne Zuführleitung (1), die die Zuführung von Polymeren in Pulverform zum Zentrum der Turbine ermöglicht,
eine einzelne Zuführleitung (6), die das Einführen von Flüssigkeit auf die außen liegenden Schaufeln (8) ermöglicht, und
eine Leitung (7) zum Abziehen der erhaltenen Dispersionen tangential von der Turbine, die in derselben Ebene angeordnet ist wie diese.
2. Vorrichtung gemäß Anspruch 1, dadurch gekennzeichnet, daß die Ebene der Turbine geneigt ist, um das Abfließen der Dispersionen zu unterstützen.
3. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Zuführleitung (1) für das , Pulver gegenüber dem Aufbau der Vorrichtung geneigt ist, daß das Pulver durch Gravitation zufließt.
