Patent number: 7138452Abstract: The present invention relates to a nanocomposite blend composition having superior barrier properties, and more particularly to a nanocomposite blend composition comprising a polyolefin resin; one or more nanocomposites having barrier properties, selected from an ethylene-vinyl alcohol (EVOH)/intercalated clay nanocomposite, a polyamide/intercalated clay nanocomposite, an ionomer/intercalated clay nanocomposite, and a polyvinyl alcohol (PVA)/intercalated clay nanocomposite; and a compatibilizer. This nanocomposite blend composition has superior mechanical strength and superior barrier properties to oxygen, organic solvent, and moisture. Also, it has superior chemical barrier properties and is applicable to single/multi-layer blow molding and film processing.Type: GrantFiled: December 11, 2002Date of Patent: November 21, 2006Assignee: LG Chem, Ltd.Inventors: Myung-Ho Kim, Shi-Ho Lee, Young-Chul Yang, Ku-Min Yang

Patent number: 7129287Abstract: A method for preparing exfoliated clay nanocomposites by in-situ polymerization comprising the steps of (a) providing a mixture of at least one type of monomer and at least one type of organophilic clay; and (b) initiating an in-situ polymerization reaction in the mixture so as to cause the at least one type of monomer to polymerize thereby forming the exfoliated clay nanocomposite. The exfoliated clay nanocomposite produces an x-ray diffraction pattern that is substantially devoid of an intercalation peak. The exfoliated clay nanocomposite may then be used as a masterbatch.Type: GrantFiled: April 29, 2003Date of Patent: October 31, 2006Assignee: The Ohio State UniversityInventors: L. James Lee, Changchun Zeng

Patent number: 7115677Abstract: A flame-retardant resin composition comprises 10 to 300 parts by weight of a flame retardant (B) and 1 to 200 parts by weight of an inorganic filler (C) (a glass fiber and/or a glass flake), relative to 100 parts by weight of a base resin (A). The flame retardant (B) comprises a polyphenylene oxide-series resin and/or a polyphenylene sulfide-series resin (B1), a phosphoric ester (B2), and a nitrogen-containing cyclic compound (B3) (for example, a polyphosphate of an amino group-containing triazine compound). The inorganic filler (C) has been treated with a surface-treatment agent or sizing agent containing a novolak epoxy resin. Such a resin composition is useful for obtaining a shaped article which has been inhibited from dripping and to which flame retardancy is highly imparted.Type: GrantFiled: November 28, 2002Date of Patent: October 3, 2006Assignee: Polyplastics Co., Ltd.Inventors: Hatsuhiko Harashina, Shinya Yamada
