| titleOfInvention | Polymer polyols and stabilizing systems |
| abstract | The present invention relates to a stabilizer suitable for the preparation of polymer polyols by in situ polymerization of one or more vinyl monomers in a stabilizing polyol, wherein the stabilizing agent comprises a stabilizing precursor derived from a polyoxyalkylene polether ether polyol having a low internal unsaturation. and has one or more functional groups and has a numerical average molecular weight of Mn corresponding to the formula Mn3000 Da x F0.39, where F is the average nominal functionality (number of functional groups) of the polyol with low internal unsaturation and the stabilizing precursor. With 0.01 to 2 moles of induced unsaturation, 1 mole of polyoxyalkylene polyether polyol having low internal unsaturation; wherein the internal unsaturation results from rearrangement of the alkylene oxide-derived units during the synthesis of the polyoxyalkylene polyol; and the induced unsaturation results from the reaction of the polyoxyalkylene polyol with a non-allyl unsaturated polyreactive unit. The stabilizing precursors and preformed stabilizers of the present invention can be used to form polymeric polyols having a higher solids content, lower viscosity, better filterability, and better particle size than polymeric polyols derived from polyols having high unsaturation.
