摘要:
Fourier transform infrared spectroscopy has been used to study quantitatively the acetylation of monodisperse polystyrene microspheres diametres ranging from 7 to 9μ. The CH2stretching infrared vibration mode at 2921 cm−1was used as the internal intensity standard. The acetylation extent could be easily measured by comparing the relative intensities of the bands of acetyl group (1678; 1415, 1359 cm−1) or the bands due to the para-substituted benzene ring to the band at 2921 cm−1from the calibration curve.
