Process for the continuous polymerization or copolymerization of trioxane

摘要

Trioxane homo-or copolymerizate is produced by continuously feeding the liquid starting material to be polymerized into a mixer in which there is present a powdered to granular oxymethylene homopolymer or copolymer which is fluidized to form a fluidized bed, the speed of feeding, catalyst concentration and polymerization temperature are coordinated to each other in suitable manner and after a polymerization reaction of at least 70 percent polymerizate is continuously or cyclically discharged from the mixer serving as reactor.
