Coated polyoxymethylenes comprising a formaldehyde scavenger comprising a lysine compound

The present invention relates to coated polyoxymethylene moldings comprising at least one polyoxymethylene homo- or copolymer A), and also, if appropriate, further additives B), which has been coated on the surface with at least one binder C) and one formaldehyde scavenger D), wherein the binder C) used comprises a polyalkylene oxide Cor a polyvinyl ester Cor a graft polymer Ccomposed of Cand Cor a mixture of these, and the formaldehyde scavenger D) used comprises at least one imidazolidin-2-one compound.

Core/jacket catalyst molding

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.

Thermoplastic elastomer compositions

Method for producing dyed moulding materials

A method for the continuous colorimetry of plastics molding compounds, which involves light being introduced, via transmitter light pipes and a sensor head, into the melt of the molding compound and the light reflected there being passed, via receiver light pipes, to a spectrometer or multirange photometer, conjugate transmitter and receiver light pipes in each case being spaced equidistantly.
