ABSTRACT:
Polymer polyol compositions are provided which are useful for the production of flexible polyurethane foams. The polymer polyol compositions are composed of (1) a high functionality polyol, (2) a subsidiary polyalkylene oxide high in polyoxyethylene content and (3) a stably dispersed polymer. The latter component is formed by in situ polymerization of low molecular weight compounds within components (1) and/or (2) used in making the polymer polyol composition. The polymer polyol compositions provide stable and non-shrinking, free-rise foam at high water levels and over a wider crosslinker and index range permitting increased density and load latitude relative to commercial high resilience polymer polyols. A process for their use and foams and articles prepared therefrom are also provided.
