Ten polypyromellitimides, seventeen poly(imide esters) and six poly(imide amides) have been synthesized. The stability of 0.5% solutions of the poly(amic acids) in DMF, and the hardness, adhesion to glass and quality of nematic liquid crystal alignment of the polyimide layers using the interference wedge method have been tested. The relationship between the chemical structure of polyimides and their properties, especially the alignment depth, is discussed.
