Abstract
Connected branch polyols comprising a core segment having a defined molecular weight, one core branch unit directly connected to each end of the core segment, at least one additional branch unit at each end connected directly or indirectly to each core branch unit, and linear polymer segments connected to the branch units are utilized in preparing a wide spectrum of polymer/polyols characterized by superior dispersion stability and viscosity to solids content relationship, the polymer/polyols in turn being employed to prepare polyurethanes having superior performance in flame retardancy tests.
