Title: Block copolymer polyimide composition soluble in ketonic and/or ethereal solvent and its production method
Inventor: KIN KOSHU
IPC: C08G73/10
Filed: 2005-08-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a block copolymer polyimide composition soluble in a ketonic and/or ethereal solvent which cannot be easily influenced by the water from the surrounding environment.  <P>SOLUTION: The solvent of a polyimide is generally a polar solvent such as N-methylpyrrolidone, N,N-dimethylformamide, N,N-dimethyacetamide and dimethyl sulfoxide. These nonaqueous solvents are however sensitive to water and very liable to absorb water, thus causing a whitening phenomenon on the surface of a polyimide. The solubility of a polyimide is improved by blocking the composition of the polyimide by using a lactone and a base as catalysts, so that the polyimide becomes soluble in a ketone and/or ethereal solvent, in which the polyimide has not hitherto been soluble. Since the ketonic and ethereal solvent is scarcely affected by water, the whitening phenomenon on the surface of a polyimide due to moisture absorption can be suppressed to the utmost.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
