ABSTRACT:
A polymer polyol is prepared by polymerizing one or more ethylenically unsaturated monomers in a polyol. A high molecular weight stabilizer having polymerizable ethylenic unsaturation and a low hydroxyl functionality is used, which leads to improved dispersion stability at reduced stabilizer level.
