The resin composition comprises a copolymer (A) formed by copolymerization of a first unsaturated monomer (a) and a second mononer (b). The first unsaturated monomer has a functional group which is bondable by hydrogen bond to a hydroxyl group. The second monomer is copolymerizable with the first unsaturated monomer. A metal oxide (B) is dispersed in the copolymer and having hydroxyl groups and hydrophobic groups at surface of the metal oxide.Type: GrantFiled: October 31, 2002Date of Patent: July 12, 2005Assignees: Nissan Motor Co., Ltd., Nihon University School Jurdical Person, Tama-TLO CorporationInventors: Shoichiro Yano, Takashi Sawaguchi, Masatoshi Chikazawa, Takashi Takei, Tomohiro Ito, Masao Nakajima, Takashi Seino, Yasuaki Kai, Shinkichi Torii, Kouichi Handa, Katsuhiko Suzuki, Kenji Uesugi

Patent number: 6911488Abstract: The present invention provides compositions that are capable of being dispersed in a target medium. The compositions include characteristic use particles entrapped within a physical entrapment phase, wherein the physical entrapment phase is dispersible in the target medium. Accordingly, the compositions of the present invention physically prevent the agglomeration or self-association of the characteristic use particles. Also disclosed are processes for manufacturing compositions that are capable of being dispersed in a target medium.Type: GrantFiled: June 21, 2002Date of Patent: June 28, 2005Assignee: Shamrock Technologies, Inc.Inventors: Charles A. Cody, Manshi Sui, Youssef Awad

Patent number: 6903148Abstract: A resin composition of the present invention comprises a polymer having functional groups and a metal oxide surface modified to form functional groups at a surface of the metal oxide and dispersed uniformly in the polymer. The functional groups of the polymer and the functional groups of the metal oxide are ionically bondable to the metal oxide and the polymer, respectively, so that the polymer and the metal oxide are bonded by ionic bonds to each other.Type: GrantFiled: March 26, 2003Date of Patent: June 7, 2005Assignees: Nissan Motor Co., Ltd., Tama-Tlo CorporationInventors: Katsuhiko Suzuki, Yasuaki Kai, Koichi Handa, Masao Nakajima, Takashi Seino, Shinkichi Torii, Tomohiro Ito, Kenji Uesugi, Masatoshi Chikazawa, Takashi Takei, Shoichiro Yano, Takashi Sawaguchi

Patent number: 6881770Abstract: A rubber composition for tire and a pneumatic tire in which the rubber composition is used improve steering performance on snowy and icy roads as well as traction performance in the forward and backward directions while reducing the recycling and manufacturing cost. The rubber composition for tire contains from 0.5 to 12 parts by weight of paper relative to 100 parts by weight of a rubber component, and preferably further contains from 5 to 100 parts by weight of silica and from 2 to 15 parts by weight of short fiber relative to 100 parts by weight of the rubber component. The paper is newspaper waste. From 10 to 100 parts by weight of carbon black may further be contained relative to 100 parts by weight of the rubber component.Type: GrantFiled: July 25, 2001Date of Patent: April 19, 2005Assignee: Sumitomo Rubber Industries, Ltd.Inventors: Yoichi Mizuno, Masato Kawase, Takao Wada, Kazuo Hochi, Ritsuo Nakayasu

Patent number: 6864310Abstract: A process for manufacturing a composition of matter from components includes combining the components to produce a blend and combining the blend with a crosslinking system to produce the composition. The components include a polymer base, a silica reinforcing filler, a silica-binding agent, and further product and process additives. Combining the components is carried out in a closed mixer comprising a piston and a pair of rotors. While combining the components, values of at least two indirect parameters and at least two direct parameters are measured at least every two minutes. The at least two indirect parameters comprise blend temperature and power absorbed by the rotors. The at least two direct parameters comprise pressure exerted by the piston and rotations of the rotors. The at least two indirect parameters are maintained within respective ranges of predetermined values by controlling one or more of the at least two direct parameters.Type: GrantFiled: October 1, 2001Date of Patent: March 8, 2005Assignee: Pirelli Pneumatici S.p.A.Inventors: Gianluigi Hotellier, Antonio Proni
