Novel aromatic-aliphatic poly(amide-imide)s containing chiral units in the main chain and hydroxyl benzamide
units in the side chain have been obtained from the step-growth polymerization of 3,5-diamino-N-(4-hydroxyphenyl)
benzamide (2) with different chiral diacid chlorides (1a1e). Theoretical calculations were done by means of computational
chemistry methods to narrate the stable conformation and orientation of each diacid chloride monomers under reaction
conditions. These polymers were characterized by conventional techniques. The resulting polymers show good thermal
stability. Other physical properties of polymers including crystallinity, inherent viscosity and morphological characteristics
were also studied.
