ABSTRACT:
The present invention relates to a process for improving the polyurethane-forming reactivity of a propylene oxide-based ethylene oxide-free polyol produced using a double metal cyanide complex catalyst by incorporating therein a minor amount of a base prior to employing the polyol in a polyurethane-forming reaction. Also claimed is the base-containing polyol composition produced in accordance with the present invention.
