METHOD FOR THE PRODUCTION OF A COLORED POLYOXYMETHYLENE COPOLYMER

The present invention relates to a method for the production of a colored polyoxymethylene copolymer by mixing a raw polyoxymethylene copolymer in particulate form, comprising 2 to 30% by weight of unreacted residual monomers, with a coloring agent in particulate form, in a degassing apparatus. In a...
