ABSTRACT:
This invention relates to novel polymer/polyol compositions consisting essentially of a polyol and a polymer of an unsaturated monomer polymerized in the polyol. The polyols in the novel compositions are polyoxyalkylene-polyoxyethylene polyols having critical oxyalkylene and oxyethylene contents, hydroxyl functionalities, hydroxyl numbers and primary hydroxyl group contents. This invention further relates to novel polyurethanes produced from such polymer/polyol compositions and especially to novel polyurethane foams having outstanding utility as seat cushions having improved static fatigue and humidity sensitivity properties.
