NANOSTRUCTURE FORMATION IN CHIRAL POLY(AMIDE-IMIDE)S BASED ON DOPAMINE MOIETY AND N-TRIMELLITYLIMIDO-L-AMINO ACIDS IN THE MAIN CHAIN

Nanostructured poly(amide-imide) (PAI) materials have been produced by polymerizing a diamine monomer, 3,5-diamino-N-(3,4-dihydroxyphenethyl) benzamide, with four trimellitic anhydride-derived, imide ring-preformed chiral amino acid-based dicarboxylic acids. Polycondensation reactions were carried o...
