3,6-Bis(dimethylamino)acridine(hexamethylbenzene)dichlororuthenium(II) was used as a tricyclic heteroatomic monomer to prepare polyimides from the corresponding dianhyrides by solution condensation. T...
Fundamental Characteristics of Solvent–Soluble Polyimide Resin as a Polymer for Hybrid Applications
Solvent Soluble Polyimide Resin a Polymer for Hybrid Applications
2010/12/28
Polyimide resin of solvent-soluble type, which is called “X-resin” in short, was discovered lately. It is soluble in dimethylacetoamid (DMAc), and new extensive applications are expected. Some physica...
