abstract |
The invention relates to a method for producing polyoxymethylene copolymers (POM) or hornopolymers by polymerising suitable monomers. The invention is characterised in that at least one partial amount of the monomers is brought into contact with a Lewis acid compound prior to polymerisation, whereby molecular sieves, having a pore diameter of less than 0,6 nm (6 A), are excluded as Lewis-acid compounds. |
