Abstract
The Raman spectrum of thermally polymerizing styrene has been recorded for temperatures of 100 and 70 °C. The intensities of the ν9 (C = C stretch mode) and ν14 (C–H bending mode) in the vinyl group are used as an indicator of the percent conversion from monomer to polymer. These intensities, normalized to that of ν24 (phenyl breathing mode), are compared to the depolarized Rayleigh intensity of polymerizing styrene. It is suggested that there is very little orientational correlation between the polymer and monomer molecules.Keywords
