A polyacetal resin composition which has high rigidity and is excellent in surface hardness, sliding properties, etc. The composition comprises 100 parts by weight of a polyacetal resin (A) and 0.01 to 100 parts by weight of a branched polyacetal copolymer (B) obtained by copolymerizing 100 parts by weight of trioxane (a), 0.01 to 10 parts by weight of a monofunctional glycidyl compound (b), and 0 to 20 parts by weight of a cyclic ether compound (c) copolymerizable with trioxane.
L'invention porte sur une composition à base de résine de polyacétal très rigide, d'une excellente dureté superficielle, et à faible coefficient de frottement. Ladite composition comprend: 100 parties en poids de résine de polyacétal (A), et de 0,01 à 100 parties en poids d'un copolymère ramifié de polyacétal (B), obtenu par copolymérisation de 100 parties en poids de trioxane (a), de 0,01 à 100 parties en poids d'un composé monofonctionnel de glycidyle (b) et de 0 à 20 parties en poids d'un composé cyclique d'éther (c) copolymérisable avec le trioxane.
