  • Polyurethane latexes, processes for preparing them and polymers prepared therewith
    Patent number: 6720385
    Abstract: Disclosed are stable aqueous polyurethane latexes prepared from prepolymer formulations including a polyisocyanate component and polyol component, wherein from 5 to 40 percent of the weight of the polyol component is ethylene oxide in the form of ethylene oxide applied as an end cap onto a propylene oxide or higher oxyalkylene polyoxyalkylene polyol, and no more than 45 percent of the weight of polyol component is ethylene oxide. These latexes are prepared without the use of organic solvents.
    Type: Grant
    Filed: April 30, 2002
    Date of Patent: April 13, 2004
    Assignee: The Dow Chemical Company
    Inventors: Rick L. Tabor, Douglas R. Moore, James J. Jakubowski, Wayne R. Willkomm, Ruben Solis

  • Polymer polyols containing halogenated aromatic monomers and polyurethane foam made therefrom
    Patent number: 5824712
    Abstract: A polymer polyol is produced by a process comprising free radical polymerizing an addition polymerizable di-(substituted phenyl)monomer (e.g., methacrylic ester of diglycidylether of tetrabromobisphenol A) component in the presence of a polyol, wherein the monomer has at least one aromatic halogen and at least one aromatic ethylenically unsaturated substituent. The polymer polyol can also be made by copolymerizing said monomer with an additional ethylenically unsaturated monomer component such as styrene and acrylonitrile. Said polymer polyols are reacted with a polyisocyanate compound forming a flame retardant polyurethane foam.
