Abstract
Provided are a polymer polyol dispersion stabilizer, which is prepared by reacting a first polyol having a hydroxyl value (OHV) of 5 to 50 mgKOH/g and an ethylene oxide content of less than 20 wt %, a second polyol having an OHV of 50 to 100 mgKOH/g and an ethylene oxide content of 20 wt % or more, and a reactive unsaturated compound having one or more carbon-carbon double bonds and two or more carbon-oxygen double bonds, and a method of preparing the same.
