Abstract
We have investigated the polyimide systems PMDA-ODA and BPDA-PDA using infrared spectroscopy, X-ray diffraction and microscopic birefringence studies. Samples cured with slow thermal ramps have been found to have less intermolecular packing orded and a greater orientation anisotropy than those cured with rapid thermal curing. This research indicates that Polyimides cure cycles may be shortened significantly, thus achieving higher productivity and greater cost efficiency.
