Patent number: 7078449Abstract: The present invention is directed to a rubber composition comprising a diene elastomer, a reinforcing white filler, and a (white filler/elastomer) coupling agent, which is bifunctional and which can be bonded to the elastomer by means of a function X. The coupling agent X function is an ester function of an unsaturated ?-? acid bearing a carbonyl group on its ? position and having the general formula (X): where R, R1 and R2 may be the same or different, where R is a monovalent hydrocarbon radical, and where R1 and R2 may be a hydrogen atom or a monovalent hydrocarbon radical. The rubber composition of the present invention is useful for the manufacture of tires or semi-finished products for tires, such as tire treads.Type: GrantFiled: June 28, 2002Date of Patent: July 18, 2006Assignee: Michelin Recherche et Technique S.A.Inventors: Salvatore Pagano, Christel Thonier, Gerard Mignani

Patent number: 7056970Abstract: A method for reducing allergenicity of natural latex rubber. The natural latex rubber, prior to its vulcanization, is admixed with aluminum hydroxide to denature the antigenic protein thus reducing the total protein level considerably. Lignin or fumed silica can also be mixed with the aluminum hydroxide to reduce the protein value in latex. Ideally, the aluminum hydroxide is characterized as having a density of approximately 2.42 g/cm3 and molecular weight of 78.00.Type: GrantFiled: April 4, 2005Date of Patent: June 6, 2006Assignee: Vystar,LLCInventor: Travis Honeycutt

Patent number: 7045569Abstract: An optical nanocomposite material has a nanoparticulate filler dispersed in a host plastic material. According to the method of making the nanocomposite material, a predetermined temperature sensitive optical vector, such as refractive index, of the plastic host material and nanoparticulate filler are directionally opposed resulting in a nanocomposite material having significantly improved stability of the refractive index with respect to temperature.Type: GrantFiled: April 5, 2002Date of Patent: May 16, 2006Assignee: Eastman Kodak CompanyInventors: John Border, Michael R. McGovern
