Abstract

A stable, low viscosity polymer polyol composition comprising a continuous phase, a disperse phase within the continuous phase, and a dispersant for enhancing the stability of the resultant polymer polyol is disclosed. In one embodiment, the dispersant is formed by polymerizing at least one acrylate monomer in a polyether polyol to form a single phase homogeneous liquid intermediate reaction product which is transesterified to form a polyol polyacrylate dispersant.
