Abstract
A method for reducing static electricity on the surface of a shaped article made of polyvinyl chloride resins, which method comprises the steps of (a) blending a surface active agent with the polyvinyl chloride resin prior to fabrication of the resin into a shaped article, (b) fabricating the resin admixed with the surface active agent into a shaped article, and (c) subjecting the shaped article to a treatment with low temperature plasma of a gas.
