Abstract
Polymer polyols and dispersions are prepared by polymerizing certain starting materials in a continuous phase. The continuous phase includes a polyol containing hydroxylmethyl groups, which is derived from a fatty acid. The dispersed phase may be, for example, a vinyl polymer, a polyurea or a polyurethane-urea.
