FT-Raman spectroscopy was used to monitor the polymerization of acrylic aci
d in aqueous solution. A simple method to avoid the noise in the background
during the signal processing via Fourier transformation was used in this w
ork. The effects of the amount of initiator used on the polymerization are
studied. When the amount of the initiator in the polymerization was increas
ed, both the rate and extent of polymerization of acrylic acid will be incr
eased.
