Abstract:
A polymer polyol composition which has a polymer content of 20 to 60 weight percent, based on total weight, a Brookfield Viscosity that is equal to or less than (a e[(0.051)(b)]) where â€œaâ€  is the viscosity of the carrier polyol and â€œbâ€  is the [(weight fraction of solids)(100)] an product stability such that essentially 100% passes through a 150 mesh screen and up to 100% passes through a 700 mesh screen produced by a free radical polymerization of the composition comprising:(a) polyol; (b) a preformed stabilizer; (c) at least one ethylenically unsaturated monomer; (d) a free radical polymerization initiator comprising at least a first active peroxide, said fir t active peroxide being present in an amount of equal to or less than 0.6 weight percent, based on the total monomer; and, (e) a chain transfer agent.
