Patent number: 8598261Abstract: A process for producing a nanocomposite of a halogenated elastomer and an inorganic, exfoliated clay includes the in-situ protonation of a modifier, which may be an alkylamine, arylamine or an alkylarylamine. This process can be integrated with a polymer halogenation process. The nanocomposite so formed has improved air barrier properties and is suitable for use as a tire innerliner or innertube.Type: GrantFiled: October 14, 2008Date of Patent: December 3, 2013Assignee: ExxonMobil Chemical Patents Inc.Inventors: Weiqing Weng, James P. Stokes, Edmund J. Stachowski, III, Molly J. Upton, Robert N. Webb, Ramesh Varadaraj, Cornelius H. Brons, David J. Lohse

Patent number: 7855258Abstract: Improved thermoplastic polymer blend compositions comprising an isotactic polypropylene component and an alpha-olefin and propylene copolymer component, said copolymer comprising crystallizable alpha-olefin sequences. In a preferred embodiment, improved thermoplastic polymer blends are provided comprising from about 35% to about 85% isotactic polypropylene and from about 30% to about 70% of an ethylene and propylene copolymer, wherein said copolymer comprises isotactically crystallizable propylene sequences and is predominately propylene. The resultant blends manifest unexpected compatibility characteristics, increased tensile strength, and improved process characteristics, e.g., a single melting point.Type: GrantFiled: February 13, 2006Date of Patent: December 21, 2010Assignee: ExxonMobil Chemical Patents Inc.Inventors: Sudhin Datta, Charles Cozewith, Periagaram Ravishankar, Edmund J.
