Abstract: A viscosity controllable highly conductive ink composition. The highly conductive ink composition comprises an organic solvent, nanoscale metal particles or metallo-organic decomposition compounds, and a thermally decomposable organic polymer. Specifically, since the thermally decomposable polymer can increase the viscosity of the highly conductive ink composition and be removed by subsequent thermal treatment, so as to decrease the impact on conductivity by organic polymer. Therefore, a viscosity-controllable conductive ink composition is obtained.

Abstract: The present invention provides a curable polyphenylene ether (PPE) resin, a composition made therefrom, and a process for preparing the resin. The process involves introducing a vinyl group-containing functional group to the terminal end of PPE by modifying the hydroxy and ester groups on the terminal end. Thus, a curable thermosetting PPE resin including a vinyl group on the terminal end can be obtained. Since the dehydrogenation of side chain methyl using n-BuLi is not conducted in the process of the present invention, the process is much easier, and the cost can be decreased.
