ABSTRACT:
A method of making antistatic vinylaromatic polymer-containing articles, and articles produced thereby, which includes immersing expandable vinylaromatic polymer-containing articles, having a blowing agent dispersed therein, in a bath containing an ethoxylated amine compound for a length of time sufficient to allow the ethoxylated amine compound to penetrate into the expandable articles to an extent such that the expandable articles, when expanded to a density of at most about 1.5 pcf, dissipate an induced 5000 volt charge to substantially 0 volts in less than 2 seconds.
