Composition For Tire Sidewalls And Other Rubber Constructions

US Patent:
6837288, Jan 4, 2005
Filed:
Jan 2, 2002
Appl. No.:
10/040778
Inventors:
Kenneth Odell McElrath - Houston TX, US
Andrew Louis Tisler - Kingwood TX, US
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
B60C 1300
B60C 100
US Classification:
152525, 525209, 525241
Abstract:

Composite Materials Comprising Polar Polymers And Single-Wall Carbon Nanotubes

US Patent:
6936653, Aug 30, 2005
Filed:
Mar 14, 2003
Appl. No.:
10/389256
Inventors:
Kenneth O. McElrath - Houston TX, US
Kenneth A. Smith - Houston TX, US
Thomas M. Tiano - Westford MA, US
Margaret E. Roylance - West Newton MA, US
Assignee:
Carbon NanoTechnologies, Inc. - Houston TX
International Classification:
C08K003/04
US Classification:
524496, 524495, 4234473, 4234472, 423445 R
Abstract:
The invention relates to a composite comprising a weight fraction of single-wall carbon nanotubes and at least one polar polymer wherein the composite has an electrical and/or thermal conductivity enhanced over that of the polymer alone. The invention also comprises a method for making this polymer composition. The present application provides composite compositions that, over a wide range of single-wall carbon nanotube loading, have electrical conductivities exceeding those known in the art by more than one order of magnitude. The electrical conductivity enhancement depends on the weight fraction (F) of the single-wall carbon nanotubes in the composite. The electrical conductivity of the composite of this invention is at least 5 Siemens per centimeter (S/cm) at (F) of 0. 5 (i. e. where single-wall carbon nanotube loading weight represents half of the total composite weight), at least 1 S/cm at a F of 0. 1, at least 1×10S/cm at (F) of 0.

Halogenated Isobutylene-Based Copolymers Having Enhanced Viscosity And Thermoplastic Compositions Thereof

US Patent:
7226962, Jun 5, 2007
Filed:
Apr 30, 2002
Appl. No.:
10/476541
Inventors:
Andy H. Tsou - Houston TX, US
Hsien-Chang Wang - Bellaire TX, US
Kenneth O. McElrath - Houston TX, US
Ilan Duvdevani - Houston TX, US
Michael K. Lyon - Houston TX, US
Mun Fu Tse - Seabrook TX, US
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
C08K 9/04
C08K 3/34
C08K 3/36
US Classification:
523213, 524445, 524493
Abstract:
The invention provides a method for increasing the viscosity of halogenated (brominated) elastomeric copolymers of a Cto Cisomonoolefin (isobutylene) and a para-alkylstryrene (p-methylstyrene) by mixing the copolymer with a silica or clay particulate filler which has been contacted with an aminosilane containing at least one Cto Calkoxy group and at least one primary, secondary or tertiary amine group. The resulting elastomer compositions are used to prepare thermoplastic elastomer blend compositions, containing more finely dispersed elastomers which results in compositions having improved mechanical properties.

Jeffrey L. Bahr - Houston TX, US
Yuemei Yang - Houston TX, US
Kenneth O. McElrath - Houston TX, US
Martin P. Grosboll - Kingwood TX, US
Aurelie Mayeux - Houston TX, US
Assignee:
Unidym, Inc. - Menlo Park CA
International Classification:
C01B 31/02
US Classification:
977845, 423461

Carbon Nanotube Particulates, Compositions And Use Thereof

US Patent:
7811542, Oct 12, 2010
Filed:
Sep 14, 2006
Appl. No.:
11/531730
Inventors:
Kenneth O. McElrath - Houston TX, US
Yuemei Yang - Houston TX, US
Kenneth A. Smith - Houston TX, US
Xiaodong Hu - Katy TX, US
Assignee:
Unidym, Inc. - Menlo Park CA
International Classification:
D01F 9/12
B82B 1/00
US Classification:
4234472, 977752
Abstract:
A method for making carbon nanotube particulates involves providing a catalyst comprising catalytic metals, such as iron and molybdenum or metals from Group VIB or Group VIIIB elements, on a support material, such as magnesia, and contacting the catalyst with a gaseous carbon-containing feedstock, such as methane, at a sufficient temperature and for a sufficient contact time to make small-diameter carbon nanotubes having one or more walls and outer wall diameters of less than about 3 nm. Removal of the support material from the carbon nanotubes yields particulates of enmeshed carbon nanotubes that retain an approximate three-dimensional shape and size of the particulate support that was removed. The carbon nanotube particulates can comprise ropes of carbon nanotubes. The carbon nanotube particulates disperse well in polymers and show high conductivity in polymers at low loadings.
