Continuous process for preparing polyoxymethylene homo- or copolymers by bulk polymerization of the monomers in the presence of cationic initiators, and also, if desired, in the presence of regulators, where during the polymerization both the monomers and the polymer are present in molten form and, if desired, the polymer is then deactivated, and the melt is discharged, cooled and pelletized, which comprises discharging, cooling and pelletizing the polymer at an elevated pressure and in the presence of a liquid.
(ZH) 在阳离子引发剂的存在下,并且如需要,在调节剂的存在下,通过单体的本体聚合制备聚甲醛均聚或共聚物的连续方法,其中在聚合过程中,单体和聚合物均以熔融形式存在,如需要,其后对聚合物进行灭活处理,将熔体卸出、冷却并造粒,该方法包括在升高的压力下和在液体存在下将聚合物卸出、冷却并造粒。
