摘要
Five new optically active poly(amide-imide)s were synthesized through the direct polycondensation reaction between chiral N,N-(pyromellitoyl)-bis-L-amino acids and methylene diphenyl-4,4-diisocyanate in a medium consisting of N-methyl-2-pyrrolidone (NMP) and xylene. The resulted polymers were fully characterized by means of Fourier transform infrared spectroscopy, elemental analyses, and solubility tests. Thermal properties of these polymers were investigated by using thermal gravimetric analysis/SDTA. All of the polymers were soluble at room temperature in polar solvents such as N,N-dimethyl acetamide, N,N-dimethyl formamide, dimethyl sulfoxide (DMSO), NMP, sulfuric acid, and para-methyl phenol. Same specific rotations of these polymers in these different solvents were obtained.
