<P>PROBLEM TO BE SOLVED: To provide a method for producing a polymer-dispersed polyol which has high compatibility with a polyol for rigid polyurethane foams, is excellent in storage stability, and can form a rigid polyurethane foam with excellent dimensional stability and good thermal insulation performance. <P>SOLUTION: In the method for producing a polymer-dispersed polyol for a rigid polyurethane foams, a monomer having a polymerizable unsaturated group is polymerized in a polyol (X), thus dispersing polymer fine particles in the polyol. The polyol (X) includes a polyether polyol (Y) having a polyoxyethylene group content of 15 mass% or higher, and the monomer having a polymerizable unsaturated group includes a fluorine-containing acrylate or a fluorine-containing methacrylate. <P>COPYRIGHT: (C)2010,JPO&INPIT |
