  • Patent number: 9023907
    Abstract: Flexible polyurethane foam is made by mixing prepolymer with foam-forming ingredients comprising isocyanate and water which react to give carbon dioxide. The prepolymer is hydroxyl-tipped, being made by reacting polyol with less than the theoretical proportion of isocyanate required to react with available hydroxyl groups of the polyol. The prepolymer is a new storage stable starting material for use in making flexible polyurethane foam, and the foam produced with the prepolymer has advantageous properties with regard to hydrolysis resistance. The prepolymer may be made with low or high viscosity by appropriate selection of the proportion of isocyanate which reacts with the polyol. At high viscosities cell structure can be advantageously controlled by appropriate gasification or degasification during foaming.

    Abstract: A polishing pad capable of maintaining a high level of dimensional stability during absorption of moisture or water includes a polishing layer including a polyurethane foam having fine cells, wherein the polyurethane foam includes a cured product of a reaction of an isocyanate-terminated prepolymer (A), a polymerized diisocyanate, and a chain extender, and the isocyanate-terminated prepolymer (A) includes an isocyanate monomer, a high molecular weight polyol (a), and a low molecular weight polyol. A method for manufacturing such a polishing pad includes mixing a first component containing an isocyanate-terminated prepolymer with a second component containing a chain extender and curing the mixture to form a polyurethane foam. The pad so made is used in the manufacture of semiconductor devices.
