Abstract
Soluble poly(p-phenylene biphenyltetracarboxamic acid) precursor was c onverted to the polyimide by thermal imidization at various conditions . The structure evolution being occurred during its thermal imidizatio n over 25-400 degrees C was investigated as a function of imidization temperature and time by X-ray scattering with synchrotron radiation so urces of Pohang Accelerator Laboratory in Korea and with conventional radiation sources. In addition, properties in the polyimide films were investigated by dynamic mechanical thermal analysis, stress-strain an alysis, prism coupling, and residual stress analysis.
