Zusammenfassung:Polyoxymethylene compositions, articles comprising these compositions, and processes of making the compositions, comprising: a) at least one polyoxymethylene polymer; b) about 0.1 to about 5 wt. % of poly alpha-1,3-glucan having a d90 particle size of 50 microns or less; c) optionally, at least one additive selected from the group consisting of nucleating agents, waxes, ultraviolet stabilizers, colorants, antioxidants, formaldehyde scavengers, lubricants, and mixtures of these; wherein an article molded from said polyoxymethylene composition exhibits a formaldehyde emission of 1 weight percent or less when measured according to TEF test method.
