Abstract (en)
This invention is directed to stable dispersions of copolymers in polyols containing added unsaturation. The polymer dispersions are prepared by reacting a polyol containing added ethylenic unsaturation and an ethylenically unsaturated monomer or mixtures thereof in the presence of a free radical catalyst characterized in that the dispersion is prepared by the Williamson synthesis or a phase transfer catalyst modification thereof employing in situ polymerization of the ethylenically unsaturated monomer or mixtures thereof in the polymer containing added ethylenic unsaturation. The unsaturated polyols prepared by these methods may be used alone or they may be blended with polyols not containing added unsaturation. The dispersions are relatively low viscosity liquids which are useful in the preparation of polyurethanes such as, for example foams and elastomers.
