Polyester resin composition

摘要

A polyester resin composition comprises a thermoplastic polyester resin; a polyester copolymer containing a monomer having at least one of an amino, imino, amido, and sulfonic acid; a layered silicate; and an antioxidant. The monomer is contained in the composition in an amount of 1-5 mole% based on total polyester content of the polyester resin composition. The antioxidant is contained in the composition in an amount of 0.01-1 mass%. A polyester resin composition comprises a thermoplastic polyester resin; a polyester copolymer containing a monomer having at least one of an amino, imino, amido, and sulfonic acid; a layered silicate; and an antioxidant. The monomer is contained in the polyester copolymer in an amount of 5-15 mole%. It is contained in the polyester resin composition in an amount of 1-5 mole% based on total polyester content of the polyester resin composition. The antioxidant is contained in the polyester resin composition in an amount of 0.01-1 mass%.
