In addition, a novel unsulfonated thermoplastic polyethersulfone comprising structural subunits derived from a non-sulfonated bis(halophenyl)sulfone bis4-fluorophenyl)sulfone and 4,4?-dihydroxyphenyl-2,6-pyridine (CAS No. 171820-16-9) is disclosed.Type: GrantFiled: July 29, 2005Date of Patent: July 1, 2008Assignee: General Electric CompanyInventors: David Roger Moore, Hongyi Zhou, Daniel Steiger, Joyce Hung, Daniel Joseph Brunelle, Hongwei Liu, Marianne Elisabeth Harmon

Patent number: 7078477Abstract: In the process of the present invention, a solvent-soluble polyimide is produced by polycondensing at least one tetracarboxylic acid component with at least one diamine component in a solvent in the presence of a tertiary amine. The tetracarboxylic acid component is selected from the group consisting of tetracarboxylic dianhydrides represented by the following formula 1: wherein R is as defined in the specification, and tetracarboxylic acids and their derivatives represented by the following formula 2: wherein R and Y1 to Y4 are as defined in the specification. Unlike the conventional techniques using an excessively large amount of a chemical imidation agent such as acetic anhydride and a chemical imidation catalyst such as triethylamine, in the process of the present invention, the solvent-soluble polyimide having a high polymerization degree is easily produced in a solvent with good productivity by using only a catalytic amount of the tertiary amine.Type: GrantFiled: June 25, 2004Date of Patent: July 18, 2006Assignee: Mitsubishi Gas Chemical Company, Inc.Inventors: Hiroki Oguro, Shuta Kihara, Tsuyoshi Bito
