Description

Verfahren zum Polymerisieren flüssiger organischer Siliciumverbindungen Es ist bekannt, daß die Polymerisation von organischen Siliciumverbindungen in der Wärme durch Luft oder Sauerstoff beschleunigt wird.Process for polymerizing liquid organic silicon compounds It is known that the polymerization of organic silicon compounds in the Heat is accelerated by air or oxygen.

Es wurde nun gefunden, daß es vorteilhaft ist, nicht das Reaktionsgemisch zu erwärmen, sondern es mit einem erhitzten Sauerstoff- bzw. Luftstrom zu behandeln.It has now been found that it is advantageous not to use the reaction mixture to heat, but to treat it with a heated stream of oxygen or air.

Das Überleiten von erhitztem Sauerstoff bzw. Luft ist besonders bei der Oberflächenbehandlung organischer Siliciumverbindungen anwendbar, bei der neben einer Trocknung zum Zweck der Verdumpfung leichtflüchtiger organischer Verbindungen eine Weiterpolymerisation des Gemisches einhergeht.The passage of heated oxygen or air is particularly important for the surface treatment of organic silicon compounds applicable, in addition to drying for the purpose of evaporating volatile organic compounds further polymerization of the mixture is associated.

Beispiel r In 5o g Orthokieselsäureäthylester, 25 ccm Alkohol und 3 ccm Wasser wird Sauerstoff eingeleitet. Nachdem sich ein Endwert der Polymerisation eingestellt 'hat, der sich nur äußerst langsam ändert, wird heißer Sauerstoff durchgeblasen, wodurch die Viskosität des Gemisches sehr schnell ansteigt und bis zur gewünschten Höhe gebracht werden kann. 0 Heißer Sauerstoff kann auch gleich von Anbeginn eingeblasen werden.Example r Oxygen is passed into 50 g of ethyl orthosilicate, 25 cc of alcohol and 3 cc of water. After a final value of the polymerization has set, which changes only extremely slowly, hot oxygen is blown through, whereby the viscosity of the mixture increases very quickly and can be brought to the desired level. 0 Hot oxygen can also be blown in right from the start.

Beispiel 2 Über einen. Film, der aus flüssigen organischen Siliciumverbindungen hergestellt ist, wird nach dem Vergießen der flüssigen Masse erhitzte Luft geleitet. Der Film erstarrt unter Polymerisation in kürzester Zeit.Example 2 About a. Film made of liquid organic silicon compounds is made, heated air is passed after the pouring of the liquid mass. The film solidifies within a very short time with polymerization.
