Polymerization of Trioxane

Abstract A survey of the possible modes of polymerization of trioxane is followed by a discussion of current ideas concerning the course of the polymerization. The polymerization, which involves ring cleavage, is characterized by a number of side reactions of the growing polyoxymethylene cations, such as chain transfer, transacetalization, and hydride shift. These reactions not only determine the nature of the end groups and the molecular weight of the resulting polyoxymethylenes, but are also responsible for their chemical and molecular uniformity. Special emphasis is placed on the role of the monomeric formaldehyde formed during the polymerization of trioxane.

Über den einfluß von reglern auf die polymerisation des trioxans

Abstract Die Untersuchung der Regelung der Trioxanpolymerisation durch verschiedene Kettenüberträger führte zu dem Ergebnis, daß während der Polymerisation als Nebenreaktion eine Hydridwanderung stattfindet. Analytische Untersuchungen erhärteten diesen Befund. Die intramolekulare Hydridwanderung liefert Methylkationen, die ihrerseits die Polymerisation oder eine Transacetalisierung auslösen. Hydridwanderung und Transacetylisierung sind für die kationische Polymerisation von Trioxan und Formaldehyd charakteristisch. Weitere Untersuchungen führten zur Auffindung neuer Regler, wie Borsäureester und alkylsubstituierte Aromaten. Ferner gelang es, Polyoxymethylene mit ungesättigten, Nitril‐ und Peroxy‐Endgruppen herzustellen.
