SYNTHESIS AND CHARACTERIZATION OF OPTICALLY ACTIVE POLY(AMIDE-IMIDE)S CONTAINING PHOTOSENSITIVE CHALCONE UNITS IN THE MAIN CHAIN

Received Date: 10 August 2009
Revised Date: 9 November 2009

A series of new optically active poly(amide-imide)s were synthesized by direct polycondensation reaction of 4,4'-diaminochalcone with several N-trimellitylimido-L-amino acids using a tosyl chloride (TsCl), pyridine (Py) and dimethylformamide (DMF) system as condensing agent. The resulting thermally stable poly(amide-imide)s were obtained in good to high yields and inherent viscosities ranging between 0.35 dL/g and 0.58 dL/g and were characterized with FTIR, 1H-NMR, CHN, Ultraviolet, TGA and DTG techniques.
