POLYOXYMETHYLENE MOULDING MATERIAL WITH IMPROVED PROCESSING STABILITY AND A REDUCED EMISSIONS TENDENCY

摘要

Moulding materials made of linear polyoxymethylene copolymers with essential ly oxymethylene units and oxyethylene units as structural units in the polymer chain, whereby the proportion of oxyethylene units in the structural units o f the polymer chain amounts to 1.5 - 2.5 mol %. The inventive moulding materia ls and moulded articles produced therefrom and optionally coloured exhibit high stability and emit extremely low quantities of formaldehyde and residual monomers. At the same time mechanical properties are high, so that the usual fields of application and processing methods can be utilized without any restrictions.
