|Title:||Kinetics of microemulsion copolymerization followed by Raman spectroscopy|
Mendizábal, E. M.
|Abstract:||In this work the kinetics of microemulsion copolymerization of styrene-methyl methacrylate using dodecyltrimethylammonium bromide (DTAB) was followed on line by low-resolution Raman spectroscopy. Reactions were carried out in a three-mouth reactor at 60°C. Raman spectra were taken every 30 seconds. Because the spectrophotometer has low resolution, the C=C peak overlaps with the aromatic ring stretch vibration and curve deconvolution was necessary. Overall conversion obtained by Raman spectroscopy agrees with that obtained by gravimetry. Because the overlap of the C=C peaks of styrene and methyl methacrylate, it was not possible to follow the individual monomer conversion by this technique.|
