POLYOXYMETHYLENE RESIN COMPOSITION AND ITS MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a composition for imparting the impact resistance and sliding property excellent in damping performance to a polyoxymethylene resin. SOLUTION: The polyoxymethylene resin composition comprises: 20-99.5 parts mass polyoxymethylene resin (A); a dynamically cross-linked elastomer (B) having 70-20% compression set (C-set); and a polymer (C) which has at least one block of a vinyl aromatic compound-conjugated diene compound random copolymer and in which the principal dispersion peak of tan δ in a viscoelastic spectrum is ≤60°C, wherein (B)/(C) is within 100/0 to 10/90 mass% and ((B)+(C)) is 0.5-80 parts mass.
