Patent number: 7501460Abstract: The present invention is a process to produce a nanocomposite of a elastomer and organic clay, e.g. an exfoliated clay, suitable for use as an air barrier. The process can include the steps of: (a) contacting a solution (10) of butyl rubber in an organic solvent with a halogen (12) to form a halogenated butyl rubber solution (16); (b) neutralizing the halogenated butyl rubber solution; (c) functionalizing at least a portion (18) of the halogenated butyl rubber; (d) mixing a dispersion (22) of clay with the functionalized butyl rubber (18) to form a masterbatch (26) comprising a polymer-clay nanocomposite; (e) combining the masterbatch (26) with the rest of the halogenated butyl rubber solution (20) to form a second mixture (28); (e) recovering the nanocomposite from the second mixture (28). The nanocomposite so formed has improved air barrier properties and is suitable for use as a tire innerliner or innertube.Type: GrantFiled: July 18, 2005Date of Patent: March 10, 2009Assignee: ExxonMobile Chemical Patents Inc.Inventors: Weiqing Weng, Caiguo Gong, Anthony Jay Dias, Robert Norman Webb, James Peter Stokes

Patent number: 6468948Abstract: Polymers (including copolymers) derived from one or more olefins, such including ethylene and C3-C20 &agr;-olefins such as propylene and 1-butene, which polymers have (a) an average ethylene sequence length, ESL, of from, about 1.0 to less than about 3.0; (b) an average of at least 5 branches per 100 carbon atoms of the polymer chains comprising the polymer; (c) at least about 50% of said branches being methyl and/or ethyl branches; (d) at least about 30% of said polymer chains terminated with a vinyl or vinylene group; (e) a number average molecular weight, Mn, of from about 300 to about 15,000 when the polymer is intended for dispersant or wax crystal modifier uses and up to about 500,000 where intended for viscosity modifier uses; and (f) substantial solubility in hydrocarbon and/or synthetic base oil. The polymers are produced using late-transition-metal catalyst systems and, preferably, inexpensive, highly dilute refinery or steam cracker feed streams that have undergone only limited clean-up steps.Type: GrantFiled: July 21, 1999Date of Patent: October 22, 2002Assignee: Infineum USA L.P.Inventors: Albert Rossi, Jacob Emert, David Edward Gindelberger, Jon Edmond Stanat, James Peter Stokes, Jaimes Sher

Patent number: 6444302Abstract: The present invention relates to a cold-drawn breathable film formed from a blend of a soft polymer component and a hard polymer component. The soft polymer component (SPC) is a copolymer of a major olefinic monomer and a minor olefinic monomer. The major olefinic monomer is either ethylene or propylene and forms the majority of the SPC. Preferred films after cold-drawing exhibit a water vapor transmission rate (WVTR) of at least 100 g-mil/m2-day.Type: GrantFiled: September 1, 2000Date of Patent: September 3, 2002Assignee: ExxonMobil Chemical Patents Inc.Inventors: Srivatsan Watson Srinivas, Patrick Brant, Francois Henri Chambon, James Peter Stokes
