Estimating the term…
To provide a method for producing a polymer-dispersed polyol which has high compatibility with a polyol for rigid polyurethane foams and is excellent in storage stability and which provides good heat-insulating performance when it is formed into a rigid polyurethane foam. Also a method for producing a polymer-dispersed polyol for rigid polyurethane foams, having polymer particles dispersed in a polyol, which comprises polymerizing a monomer having a polymerizable unsaturated group in a polyol (X), wherein the polyol (X) contains a polyether polyol (Y) having an oxyethylene group content of at least 10 mass %, and the monomer having a polymerizable unsaturated group contains a fluorinated acrylate or a fluorinated methacrylate.
