Diese kann man entsprechend der Stärke der katalytlschen Wirkung In die beiden folgenden Gruppen einteilen:For the polymerization of oxetane and its derivatives are different Known catalysts. These can be divided into the following two groups according to the strength of the catalytic effect:

1. BF3 oder BFg-Komplexe,wie BFg-Äther und BFg-Phenolat.1. BF 3 or BFg complexes, such as BFg ether and BFg phenolate.

Werden die Katalysatoren der Gruppe 1 angewendet, so sind die geeignetsten Temperaturen ziemlich niedrig. Bei Verwendung von 3,3-bls-Chlormethyloxacyciobutan als Monomer liegt die Polymerisationstemperatur z.B. zwischen -40°C und etwa Raumtemperatur. Bei -78°C tritt keine meßbare Polymerisation mehr auf. Werden Katalysatoren der Gruppe 2 verwendet, so Ist es andererseits unmöglich, Polymere mit einigermaßen guter Ausbeute zu erzeugen, wenn die Poiymerisationstemperatur nicht über 10O0C liegt.When the Group 1 catalysts are used, the most suitable temperatures are quite low. When using 3,3-bls-chloromethyloxacyciobutane as monomer, the polymerization temperature is, for example, between -40 ° C and about room temperature. No measurable polymerization occurs at -78 ° C. Catalysts of Group 2 are used, it is impossible on the other hand, to produce polymers with reasonably good yield when the Poiymerisationstemperatur is not above 10O 0 C.

Durch die Erfindung werden neue Katalysatorsysteme für die Polymerisation von Oxetan und dessen Derivaten geschaffen. Diese Systeme bestehen aus Organoaluminlumverbindungen, einigen Beschleunigern und einer geeigneten Menge Wasser.The invention provides new catalyst systems for polymerization created by oxetane and its derivatives.
