ABSTRACT:
Monomers having at least two reactive ethylenically unsaturated sites may be polymerized via a free-radical reaction in the presence of a polyol to produce a dispersant useful in preparing polymer polyols that find uses as coreactants to produce polyurethane foams. The monomers include, but are not limited to, polyethylenically unsaturated maleimides and acrylates. The dispersants prepared in this manner can be used in very small quantities, about 2 to 5 wt. % of the total polyol and still produce a styrene/acrylonitrile polymer polyol with high solids and high styrene levels.
