ABSTRACT:
Stabilizer precursors and preformed stabilizers having induced unsaturation, and prepared from low intrinsic unsaturation-containing polyoxyalkylene polyether polyols may be used to form polymer polyols of higher solids content, lower viscosity, and superior filterability and particle size than polymer polyols prepared from stabilizers derived from polyols having higher intrinsic unsaturation, even when the latter are coupled to form high molecular weight stabilizers.
