PURPOSE:To obtain anti-static polymeric materials at a low cost by heat-treating the polymeric materials at a specified temperature under the condition that the polymeric materials become wet with an aqueous solution containing stannic chloride. CONSTITUTION:As polymeric materials, polyacrylonitrile resin, polymethyl acrylate resin, polyester resin, polyamide resin, polyvinyl chloride resin, polystyrene resin, polyolefine resin, polycarbonate resin, ABS resin, melamine resin or cellolose acetate resin is used. On a surface layer of the polymeric material, a stannic chloride-made conductive layer which is generated by hydrolysis of stannic chloride is formed. The optimum aqueous solution density is between 0.5 and 5wt.%. The polymeric material is heat-treated at 60 deg.C to 140 deg.C for 2 to 60min. under a condition that it is moistened with an aqueous solution containing stannic chloride. By this method, anti-static polymeric materials can be obtained at low cost by a relatively easy method. |
