Abstract:
Preformed stabilizers useful for the production of low viscosity, high solids polymer polyols are produced by free-radical polymerization of: (a) at least one ethylenically unsaturated macromolecule or macromer with (b) at least three different ethylenically unsaturated monomers in the presence of (c) at least one free-radical polymerization initiator, and, optionally, (d) a liquid diluent, and, optionally, (e) a chain transfer agent.
