Abstract:
The present invention provides a process for preparing polyimides. The process includes cyclizing a polyimide precursor composition in a vacuum-like environment by using infrared radiation to give polyimide. The process can effectively reduce the cyclization temperature and time, thereby reducing energy and process costs.
