Abstract:
1. A polymer polyol composition 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) at least one base polyol containing active hydrogen atoms having a molecular weight of less than 3500 and a total ethylene oxide content of from 15 to 40 wt. %, and is formed in the presence of a DMC catalyst, b) at least one unsaturated monomer in an amount such that the polymer polyol will have a solids content of from 40 to 60 wt. %, and, optionally c) a preformed stabilizer, in the presence of; d) at least one radical initiator, and optionally e) a chain transfer agent.
