ABSTRACT:
A polyacetal resin composition having a volume resistivity lower than 10.sup.14 [.OMEGA..multidot.cm], which comprises (A) 100 parts by weight of a polyacetal resin and (B) 1 to 100 parts by weight of a polyether ester block copolymer which is derived from (a) a dicarboxylic acid component composed mainly of terephthalic acid, (b) a glycol component composed mainly of 1,4-butanediol and (c) a poly(ethylene oxide)glycol having a number average molecular weight of 500 to 20,000 and has a poly(ethylene oxide) dicarboxylate unit content of 20 to 95% by weight, has excellent antistatic characteristics and mechanical characteristics, and especially a high impact resistance.
