  • Method for producing polymer-dispersed polyol
    Patent number: 8084562
    Abstract: 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.

  • Process for production of urethane resin and adhesive agent
    Patent number: 7834104
    Abstract: An object of the invention is to provide a process for urethane resin production in which the molecular weight of the urethane resin can be easily controlled regardless of the kind of polyisocyanate compound and which can yield a urethane resin for use as a removable pressure-sensitive adhesive usable in extensive applications ranging from a strong-tack region to a slight-tack region.

  • METHOD FOR PRODUCING RIGID POLYURETHANE FOAM
    Publication number: 20090234038
    Abstract: To provide a method for producing a rigid polyurethane foam, whereby it is possible to obtain a rigid polyurethane foam which has a low density and good dimensional stability, and when a mixture of a polymer-dispersed polyol and a polyol for a rigid polyurethane foam to be used, is stored, the mixture is excellent in storage stability, so that a rigid polyurethane foam can be produced constantly.
