methodnfor the preparation of polyoxymethylenes by polymerization of the monomersna) in the presence of cationic initiators b) and optionallynin the presence of regulators c) and subsequent deactivation and separationnof the polymer, characterized in that the polymerizationnin a tubular reactor with static mixing elements makes whichna mixing zone, a polymerization zone and a deactivation zonenand the diameter of the tubular reactor in the mixing zone <90% of the diameternin the polymerization zone. |
