Abstract In this project novel optically active polyamides PA s poly amide imide s PAI s andsegmented poly amide imide ether urethane s PAIEU s based on L leucine L isoleucine L methionine L phenylalanine and S valine were synthesized Some physical properties of themwere investigated Starting from L isoleucine phthalic anhydride and 5 aminoisophthalic acidmoities new optically active diacid 5 3 methyl 2 phthalimidylpentanoylamino isophthalicacid MPPAIP was synthesized in three steps and the structure of this new monomer wasconfirmed by elemental analysis FT IR 1H NMR and 13C NMR spectroscopy Thenpolyamides were synthesized by direct polycondensation of MPPAIP with aromatic diaminesin the presence of the condensing agent such as TPP Py CaCl2 NMP Inherent viscosity ofthese polymers were in the range of 0 21 0 45 dL g and it showed good solubility and thermalstability It seems the existence of the imide pendent group in the polymer residue causes thisgood thermal stability In second part of this work a series of new poly amide imide s wereprepared by direct polycondensation of N trimellitylimido L isoleucine with diisocyanates The type of catalyst and solvent was optimized for the reaction of this monomer with MDI as adiisocyanate The optimized conditions was used in the other polycondensations Thesepolymers have inherent viscosities in the range of 0 13 0 48 dL g and moderate yields andthermal stability At the end of this investigation a series of PAIEU s were prepared bycopolymerization of diacids containing different amino acid and trimellitic anhydride asmonomers with MDI as a diisocyanate These polymers also showed inherent viscosity in therange of 0 25 0 76 dL g and good thermal stability All of the above polymers were fullycharacterized by FT IR 1H NMR spectroscopy and elemental analysis Also thin transparentfilms of these polymers can be prepared
