| Abstract: | Abstract Fourier transform infrared spectroscopy has been used to study quantitatively the acetylation of monodisperse polystyrene microspheres with diameters ranging from 7 to 9μm. The CH2 stretching infrared vibration mode at 2921 cm?1 was 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?1 from the calibration curve. |
