Patent number: 11702525Abstract: Although polyolefin elastomers are widely employed commodity polymers, there are shortcomings of this class of polymers for certain applications. For example, the rheological properties of some polyolefin elastomers may be insufficient to provide the green strength or low shear viscosity necessary to form stable foams, or to provide sufficient viscosity modification effects when present in a solvent. Cationomeric modification of polyolefin elastomers may alleviate these difficulties. Such polyolefin elastomers may feature a random cationomeric polyolefin copolymer comprising at least a first monomer and a second monomer, in which the first monomer is a neutral monomer and the second monomer has a side chain bearing a cationic moiety. The polyolefin elastomers may be present in foamed polyolefin compositions comprising a gas component and/or in liquid compositions comprising a solvent in which the polyolefin elastomer is dissolved.Type: GrantFiled: November 22, 2019Date of Patent: July 18, 2023Assignee: ExxonMobil Chemical Patents Inc.Inventor: Jason A.

Publication number: 20100076166Abstract: The present invention relates to a novel cyclic olefin compound, a polymer including the cyclic olefin compound, a liquid crystal alignment film including the polymer, and a liquid crystal display device including the liquid crystal alignment film. Since the polymer includes the cyclic olefin compound as a main chain, the thermal stability is excellent and the photoreactive speed is high. Accordingly, the production time can be reduced, the production cost can be reduced, and the anchoring force of the liquid crystal can be increased because the alignment property is stabilized due to the curing.Type: ApplicationFiled: March 6, 2008Publication date: March 25, 2010Inventors: Heon Kim, Sung-Ho Chun, Hee-Jin Lee, Dmitry Kravchuk, Kyung-Jun Kim, Sang-Kook Kim, Sung-Joon Oh, Hye-Ran Seong, Byung-Hyun Lee, Hye-won Jeong, Jung-Ho Jo, Yun-Jeong Lee, Dong-Hyun Oh
