This study aims to develop highly hygroscopic bio-based co-polyamides(CPs) by melt co-polycondensation of polyamide(PA) 56 salt and PA66 salt with varying molar fractions. The functional groups and the chemical structure of the prepared samples were determined by Fourier transform infrared(FTIR) spectroscopy and proton nuclear magnetic resonance(1H-NMR) spectroscopy. The relative viscosity was determined with an Ubbelohde viscometer. The melting behavior and the thermal stability of C... 相似文献
