Polymer polyols having a solids content of greater than 40 wt. %, a total ethylene oxide content of up to 25 wt. %, and a viscosity at 25° C. of less than 15,000 centistokes are produced by reacting (1) a base polyol having active hydrogen atoms with an ethylene oxide content of from 15 to 40 wt. % that has been formed in the presence of a double metal cyanide (DMC) catalyst, (2) one or more unsaturated monomers, (3) at least one radical initiator, optionally (4) a preformed stabilizer and optionally (5) a chain transfer agent. These polymer polyols (PMPOs) are useful in the preparation of polyurethane foams and elastomers.
A polymer polyol having a solids content of greater than 40% by weight, a total ethylene oxide content of up to 25%, an ethylene oxide content of up to 40% in the base polyol, and a viscosity at 25° C. of less than 15,000 centistokes comprising a reaction product of
A process for the production of a polymer polyol having a solids content of at least 40% by weight, a total ethylene oxide content of up to 25%, an ethylene oxide content of up to 40% in the base polyol, and a viscosity at 25° C. of less than 15,000 centistokes comprising reacting
