FT-RAMAN SPECTROSCOPY FOR MONITORING THE POLYMERIZATION OF ACRYLIC ACID IN AQUEOUS SOLUTION

FT-Raman spectroscopy was used to monitor the polymerization of acrylic acid in aqueoussolution. A simple method to avoid the noise in the background during the signal processing via Fouriertransformation was used in this work. The effects of the amount of initiator used on the polymerization arestudied. When the amount of the initiator in the polymerization was increased, both the rate and extent ofpolymerization of acrylic acid will be increased.
