Ionic liquids (IL)s are a new class of solvents which have interesting properties such as
nonvolatility, high ionic concentration, good thermal stability, nonflammability and can
dissolve most of organic as well as inorganic materials. Recently ILs are attracting
more attention due to their significant role in controlling the reaction as a catalyst. It is
important that ILs are the chemicals that can be applied as solvents and catalysts in
green chemistry processes. In this investigation high molecular weight and optically
active poly(amide-imide)s (PAIs) have been synthesized and their properties such as
optical activity, solubility, thermal stability were studied. Polymers were synthesized by
direct polymerization of N,N’-(4,4’-hexafluoroisopropylidenediphthaloyl)-bis-L-methionine
and various aromatic diamines in the presence of triphenyl phosphite by a new
microwave-assisted ionic liquid (MAIL) method. The compounds obtained were characterized
by elemental C, H and N analysis, solubility, FTIR, 1H NMR. Thermogravimetric
curves were also recorded. All data agree with the proposed structures.
