Among the high temperature polymers, poly(amide-imide)s (PAIs) have been known as one of promising materials due to their high thermal stability and mechanical properties together with balanced processability. Also, several properties such as optical property and thermo-dimensional stability could be controlled by modifying monomer structures. In this study, we synthesized two diacid monomers, containing an alicyclic ring, which is fastened with phenyl pendant groups, and a biphenyl group with bulky trifluoromethyl groups. Transparent PAIs were prepared by polyamidation with different ratio of diacid monomers. Detailed synthetic route and their properties will be presented.
