Patent number: 7270863Abstract: A resin-made interior member for an opening and closing body of the invention is a resin-made interior member to be attached to an inside of an outer panel of the opening and closing body and is formed by an injection molding method using a molding material of polypropylene type resin containing a reinforcing fiber and rubber and by properly setting the respective contents of the reinforcing fiber and the rubber component, the modulus of bend elasticity is improved by blending the reinforcing fiber without being accompanied with deterioration of the moldability as the material resin and the appearance of the molded product to improve rigidity of the interior member and impact resistance is assured by blending the rubber component to give the interior member with good moldability and appearance in form of the molded product and having a required rigidity and impact resistance.Type: GrantFiled: April 28, 2003Date of Patent: September 18, 2007Assignee: DaikyoNishikawa CorporationInventors: Issei Harima, Yoshiaki Saito, Takahiro Tochioka

Patent number: 7244484Abstract: The present invention provides compositions useful as a barrier layer in, for example, packaging products. The compositions generally comprise a blend of (i) a polyester resin, preferably an aromatic polyester resin such as polyethylene terephthalate (PET) and (ii) a polyamide material (e.g., MXD6). The blend optionally may further comprise (iii) an oxygen scavenging material. The present invention also provides containers (e.g., containers formed by expansion of preforms) having a multilayered body-forming portion including: a core layer comprising the aforementioned blend; and inner and outer layers of a formable polymer composition. The present invention also provides methods of making such containers.Type: GrantFiled: October 31, 2001Date of Patent: July 17, 2007Assignee: Valspar Sourcing, Inc.Inventors: Paul E. Share, Keith R.

Patent number: 7241403Abstract: PROBLEM TO BE SOLVED: To provide a production method for a thermoplastic resin composition, composed of a polyphenylene ether and a polyamide, having an electric conductivity, and excellent in balance of fluidity and impact strength, by producing with a specific process, and to provide the thermoplastic resin composition obtained thereby. SOLUTION: The thermoplastic resin composition is composed of the following component (A)-(E), wherein a weight ratio of (A)/(B) is 5/95-70/30, an amount of (C) is effective to phase-solvate (A) and (B), the amount of (D) is 0.8-10 pts.wt. per the total 100 pts.wt. of (A) and (B), and the amount of component (E) is 5-40 pts.wt. per the total 100 pts.wt. of (A) and (B). The production method for the thermoplastic resin composition is provided. (A): a polyphenylene ether, (B): a polyamide. (C): a phase-solvating agent, (D): an electrically conductive carbon black and/or a fine fibrous carbon, and (E) an improving agent for shock resistance.Type: GrantFiled: May 29, 2003Date of Patent: July 10, 2007Assignee: General Electric CompanyInventors: Robert Hossan, Sai-Pei Ting

Patent number: 7241817Abstract: The present invention relates to a process for grafting an unsaturated monomer onto a fluoropolymer, having the steps of: a) melt blending the fluoropolymer with the unsaturated monomer; b) forming the blend obtained in a) into films, sheets, granules or powder; c) exposing the products from step b), in the absence of air, to photon (?) or electron (?) irradiation with a dose of between 1 and 15 Mrad; and d) optionally treating the product obtained at c) in order to remove all or part of the unsaturated monomer that has not been grafted onto the fluoropolymer. Structures made with these materials are barriers to many fluids and in particular to petrol and to air-conditioning fluids and may be formed into bottles, tanks, containers, pipes, hoses and vessels of all sorts. They may also be converted into films with which packaging is made.Type: GrantFiled: June 2, 2004Date of Patent: July 10, 2007Assignee: Arkema FranceInventors: Anthony Bonnet, Barbara Ramfel, Fabrice Chopinez, Karine Triballier, Michael Werth, Thierry Pascal
