  • Felted hydrophilic ester polyurethane foams
    Patent number: 6841586
    Abstract: An ester polyurethane foam is prepared by reacting a mixture of one or more polyester polyols with one or more isocyanates and one or more silicone surfactants in the presence of a blowing agent, such as water, and other additives, such as catalysts. The cured foam is chemically treated in a caustic solution and is then felted (compressed under heat and pressure) to form a hydrophilic ester polyurethane foam having a water absorption rate of at least 30 pounds of water per square foot per minute (1.44 kPa/min). The foam also has greater water holding capacity and wet strength than cellulose.
    Type: Grant
    Filed: December 23, 2003
    Date of Patent: January 11, 2005
    Assignee: Foamex, L.P.
    Inventors: Sharon A. Free, Charles V. Rose

  • Process for the preparation of polyol polymer dispersions
    Patent number: 6143802
    Abstract: Polymer polyols and polymer-modified polyols having substantially no transition metal content in the polyol continuous phase may be prepared from encapsulative double metal cyanide complex-catalyzed polyoxyalkylene polyether base polyols without substantial removal of double metal cyanide complex catalyst residues from the base polyol and subsequent in situ polymerization of one or more polymerizable monomers.
    Type: Grant
