METHOD FOR PRODUCING POLYOXYMETHYLENES

The invention relates to a method for producing polyoxymethylenes by cationic polymerization of the monomers a) in the presence of initiators b) and optionally in the presence of regulators c) and subsequent deactivation and removal of the polymer. The inventive method is characterized in that durin...

Beschreibung
Zusammenfassung:	The invention relates to a method for producing polyoxymethylenes by cationic polymerization of the monomers a) in the presence of initiators b) and optionally in the presence of regulators c) and subsequent deactivation and removal of the polymer. The inventive method is characterized in that during the entire polymerization the overall amount of proton donors is less than 5.000 ppm.
