ABSTRACT:
Adducts, improved polymer-polyols and improved polyurethane foams are provided. The adducts are produced by reacting suitable polyol and epoxy co-reactant to essentially eliminate all epoxy groups. The polymer-polyol is produced by polymerizing suitable ethylenically unsaturated monomer in the adduct or in the adduct forming mixture; in the later case the adduct forming reaction and the polymerization reaction occur simultaneously to produce the polymer-polyol. Polyurethane foams are produced by the usual method but employing the novel adduct or polymer-polyol of the present invention.
