ABSTRACT:
This invention relates to a process for preparing polyisocyanate-based polymers which have the ability to dissipate static electrical charge. The polymers are rendered semi-conductive by having incorporated into them an anti-static additive which comprises an ionizable metal salt dispersed in a polyalkylene carbonate polyol.
