Abstract In this study different series of optically active poly amide imide s PAI s andpoly amide imide ether urethane s PAIEU s based on a pre formed imide ring diacidmonomer and L leucine were successfully synthesized and the effect of different reactionparameters and structural characteristics on their physical properties were studied First different series of optically active PAIs were prepared by the directpolycondensation reaction of bis p amido benzoic acid N trimellitylimido L leucine BPABTL 5 as a diacid monomer with 4 4 methylene bis 4 phenylisocyanate MDI 6 tolylene 2 4 diisocyanate TDI 7 hexamethylene diisocyanate HDI 8 andisophorone diisocyanate IPDI 9 The polymerization reactions were performed undermicrowave irradiation solution polymerization under graduate heating and refluxcondition in the presence of pyridine Py dibuthyltin dilurate DBTDL triethylamine TEA as a catalyst and without catalyst respectively The resulting polymers haveinherent viscosities in the range of 0 09 1 10 dL g All of the above polymers were fullycharacterized by FT IR spectroscopy 1H NMR spectroscopy elemental analyses CHN specific rotation and thermal analyses methods In the other part of this study BPABTL was used as a constituent building of hardsegment of different series of optically active segmented PAIEUs The solutioncopolymerization reactions were performed under graduate heating in the presence ofdifferent catalysts and without catalyst respectively The optimized reaction conditionsaccording to catalysts reaction solvent reaction temperature and time were obtained andwere used for other investigations All of the above PAIEUs were fully characterized byFT IR spectroscopy 1H NMR spectroscopy elemental analyses CHN and specificrotation The effect of different reaction parameters and structural characteristics such assoft segment length soft segment type hard to soft segment content ratio polymerizationmethod one step Vs two step on their physical properties including viscosity phaseseparation crystallinity thermal resistance solvent resistance environmental resistance and dynamic thermal behavior of these PAIEUs were studied Their different propertieswere studied by solubility test FT IR SEM WAXS DMTA DSC and TGA techniques
