Patent number: 9061253Abstract: [Problem] Diamine and carboxylic dianhydride for polymerizing a hexafluoroisopropylidene group-containing polyimide are limited in chemical structure when developed into a polyimide membrane, so that it is difficult to design a chemical structure with consideration paid to the strength and separation performance of a gas separation membrane. A gas separation membrane easily soluble in an organic solvent, excellent in formability so as to be readily usable for a gas separation membrane, and excellent in gas separation performance is obtained. [Solution] A gas separation membrane, including: a polyimide that contains a repeating unit represented by general formula (1). [In the formula (1), R1 is a divalent organic group and R2 is a tetravalent organic group, R1 containing a 2-hydroxy-1,1,1,3,3,3-hexafluoroisopropyl group (—C(CF3)2OH)].Type: GrantFiled: May 30, 2012Date of Patent: June 23, 2015Assignee: Central Glass Company, LimitedInventors: Kazuhiro Yamanaka, Tsuyoshi Ogawa, Takeshi Suda, Hiroki Uoyama

Adhesive Composition, Bonding Method Using Adhesive Composition, and Separation Method After Bonding
Publication number: 20140116615Abstract: An adhesive composition according to the present invention contains a polymerizable group-containing siloxane compound, a polymerization initiator and an ultraviolet-absorbing blowing agent. This adhesive composition enables quick bonding of substrates etc. by light irradiation or by heating such that the bonded substrates can secure adhesion and heat resistance to withstand grinding etc. and, when no longer needed to be bonded, can be easily separated from each other by ultraviolet light irradiation and is thus suitable for use as an adhesive composition for manufacturing of semiconductor devices (particularly for manufacturing of semiconductor devices with through-silicon vias).Type: ApplicationFiled: October 24, 2013Publication date: May 1, 2014Applicant: Central Glass Company, LimitedInventors: Tsuyoshi OGAWA, Kiminori SATO, Hiroki UOYAMA, Kazuhiro YAMANAKA
