Abstract: Polyacetal resin compositions capable of providing a molded article having exceptionally reduced surface gloss characteristics but which maintain the inherent mechanical properties and moldability of polyacetal resin include (A) 100 parts by weight of a polyacetal base resin and, incorporated therein, (B) between 1 to 50 parts by weight of a polyalkylene terephthalate copolymer having a melt flow temperature of 210.degree. C. or below, and (C) between 0.1 to 10 parts by weight of an isocyanate or isothiocyanate compound, or a derivative thereof.

Abstract: A low surface gloss polyacetal resin composition includes (A) 100 parts by weight of a polyacetal base resin and (B) between about 0.1 to 40 parts by weight of a silicon graft copolymer which is the radical copolymerization product of (a) an acrylic-modified silicone with (b) a radical-polymerizable monomer. Optionally, the compositions may have a weathering (UV-light) stabilizer. Molded articles formed of the compositions exhibit low surface gloss and weather-resistance properties and are thus usefully employed in end-use applications where such attributes are required (e.g. automotive trim parts, electronic components, and the like).
