VERFAHREN ZUR ABSCHÄTZUNG VON DER AUFLÖSUNGSGESCHWINDIGKEIT VON POLYIMID
摘要
A method of evaluating the dissolution rate of a polyimide by Raman spectroscopy, wherein the Raman spectral intensity I(a) of imide groups contained within the polyimide is measured, and I(a) is then compared with the Raman spectral intensity I(b) of imide groups contained within a polyimide with a known dissolution rate. The polyimides are preferably obtained using an aromatic tetracarboxylic dianhydride and/or an aromatic diamine.
