    摘要: 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.

    摘要: Provided herein is a translucent white polymer composition suitable for use as a safety glass interlayer. The translucent white polymer composition comprises a pigment and a polymeric resin that comprises an ionomer of an ethylene acid copolymer. Alumina (Al2O3) and alumina trihydrate (Al(OH)3; “ATH”) are preferred pigments. The translucent white polymer composition is useful in various molded articles. The translucent white polymer composition is particularly useful as an interlayer in glass laminates, including safety glass laminates and structural glass laminates. Further provided herein are methods of making the translucent white polymer composition, the articles and the glass laminates.
