Patent number: 6326424Abstract: It has been unexpectedly determined that isoprene-butadiene rubber having a high glass transition temperature within the range of about −40° C. to about −25° C. (high Tg IBR) can be loaded with silica as a filler and utilized in manufacturing tire treads that have outstanding performance characteristics. For instance, such tire treads offer lower hysteresis at high temperatures (improved rolling resistance) and higher hysteresis at low temperatures (improved wet traction characteristics). By utilizing high Tg IBR in tire tread compounds, the maximum benefits of silica compounding can be realized without the need for solution or emulsion styrene-butadiene rubber (SBR) in the tread rubber formulations. The tire tread rubber formulations of this invention will normally contain about 20 phr (parts per 100 parts of rubber) to about 100 phr of the high Tg IBR.Type: GrantFiled: October 12, 1999Date of Patent: December 4, 2001Assignee: The Goodyear Tire & Rubber CompanyInventors: Olivier Louis, Adel Farhan Halasa, Wen-Liang Hsu

Publication number: 20010031811Abstract: Describes durable coating compositions and a process for the preparation of durable, broad-band antireflective coatings on organic polymeric host materials and photochromic organic polymeric host materials. The coating compositions consist essentially of a silane monomer mixture comprising glycidoxyalkylalkoxysilane and alkylalkoxysilane(s) with or without tetraalkoxysilanes; water-soluble organic polymer; a leveling amount of nonionic surfactant; a solvating amount of lower aliphatic alcohol; a catalytic amount of water-soluble acid; and water. The coating compositions may optionally contain fluorinated silane(s). Also describes a process for preparing antireflective coatings comprising the steps of coating a polymeric host material with the durable coating composition; curing the coating; treating the cured coating with an aqueous acidic solution to produce a graded refractive index; removing residual acid; and further curing the coating.Type: ApplicationFiled: February 28, 2001Publication date: October 18, 2001Inventors: Huawen Li, Bhima R.

Patent number: 6297302Abstract: Disclosed is a composition comprising a crosslinked product of a liquid composition which comprises (a) a fluorosilicone, (b) a crosslinking agent and (c) a thermal stabilizing agent comprising a reaction product of (i) a cyclic unsaturated-alkyl-group-substituted polyorganosiloxane, (ii) a linear unsaturated-alkyl-group-substituted polyorganosiloxane, and (iii) a metal acetylacetonate or metal oxalate compound. The crosslinked fluorosilicones can be employed as intermediate or outer layers of electrostatographic fuser members, electrostatographic intermediate transfer belt materials and the like. They are useful in applications wherein materials possessing desirable release characteristics, surface energies, electrical characteristics, oil resistance properties, or solvent resistance properties exhibited by fluorosilicone elastomers are desirable.Type: GrantFiled: August 17, 1999Date of Patent: October 2, 2001Assignee: Xerox CorporationInventors: George J. Heeks, David J. Gervasi, Arnold W. Henry, Santokh S. Badesha
