Abstract:
1. A, stable, ultra-high solids polymer polyol composition, comprising the reaction product of: (A) a base polyol; (B) from 7.5% to 35% by weight, based on 100% by weight of the polymer polyol, of a high potency preformed stabilizer which comprises and (C) at least one ethylenically unsaturated monomer; in the presence of (D) at least one free-radical polymerization initiator; and (E) a chain transfer agent; wherein the polymer polyol has a solids content greater than 60% by weight, and the polymer polyol has a kinematic viscosity less than or equal to (X e [−4.5×LN(1−(Y/100))] ) wherein: X: represents the kinematic viscosity of the base polyol, Y: represents the total solids content expressed as weight percent, LN: represents the logarithm to natural base, and the polymer polyol has product stability such that essentially 100% passes through a 150 mesh screen and at least about 99% passes through a 700 mesh screen.
