摘要：

Long chain semiaromatic polyamides with high molecular weight were synthesized by the reactions of undecanediamine with various aromatic diacids, and characterized by fourier transform infrared spectra (FT-IR) and nuclear magnetic resonance (1H-NMR). The thermal behaviors were determined by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The solubility, dynamic mechanical, physical and mechanical properties of the polyamides were also investigated. The experimental results show that the polyamides with high molecular weights are obtained only the PH value of the polyamides salt are in the range of 7.2-7.4. The melting temperatures and the glass transition temperatures of the polyamides increase with the increase of the rigidity of aromatic diacids, and are near to those of poly(nonamethyleneterephthalamide) (PA9T).
