    摘要: The polyacetal resin composition contains about 0.01–10 parts by weight of a glyoxyldiureide compound per 100 parts by weight of polyacetal resin. The glyoxyldiureide compound includes glyoxyldiureide and its derivatives (metal salts etc.). Optionally, about 0.01–10 parts by weight of a basic nitrogen-containing compound is further added. The basic nitrogen-containing compound includes melamine, melamine resin, and polyamide resin. Further, an antioxidant may be further added. The above composition contributes to stability, particularly heat stability, of polyacetal resin and suppression of emission of formaldehyde.

    摘要: About 0.001 to 1 part by weight of a phenol component (B1) and/or about 0.001 to 10 parts by weight of an amino acid (B2) are added relative to 100 parts by weight of a polyacetal resin (A) to prepare a polyacetal resin composition. The phenol component (B1) may be a novolak phenol-series resin, a phenol aralkyl-series resin, a polyvinyl phenol-series resin, a polyhydric phenol, a polyphenol, a catechin compound, or a lignin. The amino acid (B2) may be an α-amino acid, a β-amino acid, a γ-amino acid, a δ-amino acid, or a derivative of an amino acid. The polyacetal resin composition may further contain an antioxidant, a heat stabilizer, a processing stabilizer, a weather (light)-resistant stabilizer, or a coloring agent. The polyacetal resin composition ensures marked inhibition of formaldehyde emission.

    摘要: An improved synthetic resin composition is provided that consists essentially of 100 parts by weight of a resin component composed of in excess of 50 up to 99 parts by weight of a liquid crystal polyester resin (A) capable of forming an anisotropic melt phase, and 1 up to less than 50 parts by weight of a polyalkylene terephthalate resin (B), to which has been added 0.001 to 5 parts by weight of a phosphorus ester (C) (e.g., a pentaerythritol phosphite). The presence of the phosphorus ester in the specifically defined polymer blend has been found to greatly impede the formation of deleterious mold deposits, and to make possible the formation of quality molded articles on an expeditious basis having good mechanical properties.
