Abstract
Coloring study in blends of polyamide(PA6) and N-N′-ethylene-bis(tetrabromophthalimide)(NEBT) has been characterized by several techniques.CS930 double wavelength lamella scanner was employed to measure change of color.The existence of hydrogen bonding in PA6/N-N′-ethylene-bis(tetrabromophthalimide)(PA6NET) was investigated with Fourier transform infrared(FT-IR).FT-IR spectra at room temperature revealed that there is essentially hydrogen bonding between PA6 and NEBT.The temperature-dependent behavior of both PA6 and PA6NET was studied by temperature-FT-IR spectroscopy.The results show that stability of hydrogen bonding between pure PA6 and NEBT is better than that of pure PA6.And crystallization property was studied by differential scanning calorimetry(DSC).
