Patent number: 7670501Abstract: Microcellular polyurethane flexible foams having densities no greater than 0.3 g/cc which are suitable for use as lightweight shoe sole components are produced with carbon dioxide in an amount such that the polyurethane-forming mixture has a free rise density of from about 0.03 to about 0.3 g/cc. At least a portion of that carbon dioxide is dissolved as a gas into one or both of the reaction components. The amount of dissolved carbon dioxide must be such that the froth density of the isocyanate and/or isocyanate-reactive component(s) in which the carbon dioxide is dissolved will be from about 0.1 to about 0.8 g/cc. Additional carbon dioxide may be formed by the reaction of water and isocyanate during the polyurethane-forming reaction but the total amount of CO2 present should be controlled to ensure that the polyurethane-forming mixture has a free rise density of from about 0.03 to 0.3 g/cc.Type: GrantFiled: May 27, 2005Date of Patent: March 2, 2010Assignee: Bayer MaterialScience LLCInventors: Usama E. Younes, David M. Baily, Charles R. Carpenter

Patent number: 7651635Abstract: The invention provides a composition of matter and a method of its use in preventing unwanted polymerization reactions. The composition comprises an inhibitor and a retarder. The inhibitor is highly effective. The retarder is reliable under extreme and emergency situations. The inhibitor can be an alkylhydroxylamine. The retarder can be a 7-cyano-quinone methide. The combination of the inhibitor and retarder has been found to be far more effective than expected.Type: GrantFiled: February 5, 2009Date of Patent: January 26, 2010Assignee: Nalco CompanyInventor: Vincent E.
