ABSTRACT:
An antistatic agent imparting excellent antistatic property to the polyacetal resins and the polyacetal resins using this antistatic agent. The antistatic agent for polyacetal resins is obtained by including polyalkylene polyols or metal salt-dissolved polyalkylene polyols in a basic carbonate of metals consisting chiefly of alkali metals and aluminum having a porous volume of 0.5 cc/g or larger over a region of meso pores to quasi-macro pores of porous radii of from 200 to 1000 angstroms or in an anion exchanger thereof, said porous volume being greater than 30% of the whole porous volume, and a polyacetal resin composition in which said antistatic agent is blended. The antistatic agent of the invention imparts stable antistatic properties to the above resins and is little dependent upon the environment, and further does not lose thermal property or mechanical strength that occurred with the conventional antistatic agents. Therefore, the resin composition can be extensively used in the field of engineering plastics.
