POLYMER/POLYOLS AND POLYURETHANE DERIVATIVES THEREOF

摘要

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 polyoxyalkylenepolyoxyethylene 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.
