Patent number: 9687833Abstract: An optically active compound production method using a column reactor, a column for column reactor is charged with asymmetric catalyst particles to produce the column reactor, and reaction compound is introduced into column reactor to bring reaction compound into contact with asymmetric catalyst particles, whereby reaction compound is converted to optically active compound. Asymmetric catalyst particles are preferably resin particles that are prepared from a monomer composition containing a proline derivative monomer having unsaturated bond and radical polymerization initiator and serve as catalyst for enamine mechanism reaction. Asymmetric catalyst particles are preferably resin particles prepared by micro-channel method including injecting monomer composition into continuous phase to thereby form droplets of monomer composition in continuous phase and then heating droplets to cause proline derivative monomer having an unsaturated bond to undergo radical polymerization.Type: GrantFiled: June 3, 2014Date of Patent: June 27, 2017Assignee: DEXERIALS CORPORATIONInventors: Hiroki Kanaya, Mamiko Nomura

Patent number: 8445621Abstract: A novel polyimide resin is formed by imidizing a diamine component including an amide group-containing siloxane diamine compound represented by the following formula (1) and an acid dianhydride component including an aromatic acid dianhydride such as 3,3?,4,4?-diphenylsulfone tetracarboxylic dianhydride. This novel polyimide resin utilizes a novel polyimide resin into which a reaction group capable of reacting with a crosslinking agent to form a crosslinking point is pre-introduced before imidization. The novel polyimide resin can confer a comparatively low elastic modulus and heat resistance to a dry film or a photosensitive cover film formed from a photosensitive polyimide resin composition containing the novel polyimide resin. In the formula (1), R1 and R2 are each independently an optionally-substituted alkylene group, m denotes an integer of 1 to 30, and n denotes an integer of 0 to 20.Type: GrantFiled: August 20, 2008Date of Patent: May 21, 2013Assignee: Sony Chemical & Information Device CorporationInventors: Tomoyasu Sunaga, Hiroki Kanaya, Mamiko Nomura, Junichi Ishii

Patent number: 7592119Abstract: The developability of a photosensitive polyimide resin composition with a weakly alkaline aqueous solution is improved without reduction in the solubility in general-purpose organic solvents even when a part of the diamine component is replaced with a diaminopolysiloxane-based compound or a bis(aminobenzoate)-based compound in order to reduce the warpage characteristics of the photosensitive polyimide resin composition by reducing its modulus of elasticity. The photosensitive polyimide resin composition is capable of being developed in a positive manner with a weakly alkaline aqueous solution and is soluble in an organic solvent. The photosensitive polyimide resin composition contains: a polyimide resin including a polyimide unit represented by formula (1) and a polyimide unit represented by one of formulas (2) and (3); an analogue of melamine cyanurate; and an analogue of diazonaphthoquinone.Type: GrantFiled: January 23, 2008Date of Patent: September 22, 2009Assignees: Sony Corporation, Sony Chemical & Information Device CorporationInventor: Mamiko Nomura

Publication number: 20090148776Abstract: A liquid absorbing sheet has a liquid-absorbing resin layer that can effectively absorb the nonaqueous electrolyte solution used in nonaqueous electrolyte secondary cells that make nonaqueous electrolyte battery packs (in particular, lithium ion-based nonaqueous secondary battery packs). The liquid-absorbing resin layer is obtained by irradiating a particular monomer composition with UV rays or other energy rays to polymerize the monomer composition. The monomer composition contains a monofunctional monomer component (A) having a polyethylene glycol acrylate monomer and an amide bond-containing acrylic monomer; and a polyfunctional monomer component (B).Type: ApplicationFiled: February 4, 2009Publication date: June 11, 2009Applicant: SONY CHEMICAL & INFORMATION DEVICE CORPORATIONInventors: Kouki Hatsuda, Yasuhiro Fujita, Hironobu Moriyama, Mamiko Nomura

Patent number: 6927274Abstract: Polyimide precursors contained in resin compositions of the present invention have a polymer structure unit represented by formula (1) below: wherein chemical structure A2 includes an alicyclic compound but not an aromatic compound such as a benzene ring so that they provide excellent light transmission over a wide wavelength range. The polyimide precursors are imidized at 7.5% or more and 36% or less so that they are less soluble in developing solutions and therefore are not dissolved in the developing solutions at unexposed parts. Thus, the resin compositions of the present invention can be used to form a resin film having a precise pattern by exposure and development.Type: GrantFiled: October 24, 2003Date of Patent: August 9, 2005Assignee: Sony Chemicals Corp.Inventors: Mamiko Nomura, Masatoshi Hasegawa, Junichi Ishii, Tadashi Akamatsu
