Abstract: Specific polyoxymethylene copolymers are described with a weight-average molar mass (MW) in the range from 5000 to 15 000 g/mol, and processes are described for producing these by polymerization of trioxane and optionally of comonomers in the presence of at least one cationic initiator and of at least one di(C1-6-alkyl) acetal as regulator.
