Publication number: 20090275676Abstract: A process for particulate-resin production from an aqueous solution containing resin particles by recovering the particulate resin from the solution. In recovering the particulate resin from the aqueous solution, a lubricant is added in an amount of 0.05-5 parts by weight per 100 parts by weight of the resin ingredient contained in the particulate resin and a dispersant is added in an amount 0.1 to 1 time by weight the amount of the lubricant. Thus, a particulate resin excellent in transparency and blocking resistance can be obtained. In particular, a particulate isobutyrene block copolymer resin can be stably produced.Type: ApplicationFiled: August 29, 2006Publication date: November 5, 2009Applicant: KANEKA CORPORATIONInventors: Keizo Hayashi, Tomoyuki Yoshimi

Publication number: 20090131556Abstract: It is an object of the present invention to provide an epoxy resin composition in which a ratio of the time between the beginning of injection and the vitrification of the epoxy resin composition to the time during which a state of liquid having such a viscosity that the epoxy resin composition can be injected is held after the beginning of injection is small, and a material in which a resin cured product has less-coloring and the appearance and the surface smoothness of the fiber-reinforced composite materials are excellent in order to enable to mold fiber-reinforced composite materials having high fiber volume fraction (Vf) and excellent mechanical properties or fiber-reinforced composite materials having a large size in a short time. The above problem can be achieved by an epoxy resin composition for a fiber-reinforced composite material comprising an epoxy resin, an acid anhydride curing agent and an organic phosphorus compound, wherein the organic phosphorus compound is contained in an amount of 0.Type: ApplicationFiled: April 13, 2007Publication date: May 21, 2009Applicant: Toray Industries, Inc.Inventors: Shiro Honda, Go Tanaka

Publication number: 20090117388Abstract: Disclosed is a phenol aralkyl epoxy resin having a structure wherein at least a phenol or a naphthol is bound by using an aralkyl group as a linking group and a structure represented by formula (1) below, while satisfying the condition 1 below. This epoxy resin is excellent in workability during production of a composition and is easy to control quality. Condition 1: The following relation (?) is satisfied with A being the hydroxyl equivalent (as measured in accordance with JIS K 0070) of a phenol-modified epoxy resin obtained by adding an equivalent molar amount of phenol relative to the epoxy equivalent of the epoxy resin, and B being the epoxy equivalent of the epoxy resin.Type: ApplicationFiled: October 16, 2006Publication date: May 7, 2009Inventors: Masataka Nakanishi, Katsuhiko Oshimi, Kazuyuki Ohhashi, Toru Kurihashi

Patent number: 7456233Abstract: An adhesive formulation comprising at least a reinforcing phase, a liquid phase and an adsorbent phase. The adsorbent phase, in particle form, has a surface coating which renders the adsorbent phase non-interactive and non-reactive with at least the reinforcing phase and liquid phase.Type: GrantFiled: February 16, 2005Date of Patent: November 25, 2008Assignee: Nordson CorporationInventor: Laurence B.

Patent number: 7317044Abstract: The present invention relates to a polymer powder composed of polyamide or of copolyamides, which also comprises flame retardant, in particular phosphonates, to a layer-by-layer process which selectively melts regions or selectively binds them, and also to moldings produced from this polymer powder. Compared with conventional products, the moldings constructed using the powder of the invention exhibit marked advantages in flammability and combustibility and drop behavior, particularly with respect to UL® (Underwriters Laboratories) classification. Furthermore, moldings produced from polymer powder of the invention have adequately good mechanical properties when compared with moldings based on polymer powders without flame retardant, in particular in terms of modulus of elasticity and tensile strain at break. In addition, these moldings also have a density close to that of injection moldings.Type: GrantFiled: July 16, 2004Date of Patent: January 8, 2008Assignee: Degussa AGInventors: Sylvia Monsheimer, Maik Grebe, Franz-Erich Baumann
