Publication number: 20100187001Abstract: 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: ApplicationFiled: August 20, 2008Publication date: July 29, 2010Applicant: SONY CHEMICAL & INFORMATION DEVICE CORPORATIONInventors: Tomoyasu Sunaga, Hiroki Kanaya, Mamiko Nomura, Junichi Ishii

Patent number: 7763698Abstract: Materials and a method are provided whereby polymers with least 0.5 mole % of the pendant group or end group containing —Si(OR?)3 (where R? is H, an alkyl group, Na, K, or NH4) are used to control aluminosilicate scaling in an industrial process having an alkaline process stream such as a pulping mill process stream. When materials of the present invention are added to the alkaline process stream, they reduce and even completely prevent formation of aluminosilicate scale on equipment surfaces such as evaporator walls and heating surfaces. The present materials are effective at treatment concentrations that make them economically practical.Type: GrantFiled: April 3, 2008Date of Patent: July 27, 2010Assignee: Cytec Technology Corp.Inventors: Donald P.
