Document Type and Number:
Japanese Patent JP5841914
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a polyacetal resin composition and a molded article of the same, having electrostatic diffusivity and little separation of conductive fillers when sliding with other materials.SOLUTION: Provided is a polyacetal resin composition containing a polyacetal resin (I), a block copolymer (II) represented by any of the following formulas (1) to (5), conductive carbon black (III) and an acid-modified polyolefin resin (IV), and having a specific volume resistance of 1.0×10to 1.0×10Ω cm: A-B-A (1); (A-B)(2); B-(A-B)(3); (A-B)-A (4); and (A-B)-X (5). In the formulas (1) to (5), A represents a polymer block having a vinyl aromatic monomer unit as a main constituent; B represents a polymer block having a conjugated diene monomer unit as a main constituent; n is an integer of 2 to 10; X represents a residue of a polyfunctional compound; and m is an integer of 2 to 7.
