Abstract
The polymerization of a commercial polyester resin was investigated by differential scanning calorimetry (DSC). The conversion profiles were obtained in the temperature range 60-80 degrees C. The autocatalytic model satisfactorily describes the experimental data. Fourier transfor m infrared spectroscopy (FTIR) measurements were also made in order to obtain both the styrene and polyester unsaturations conversions, whic h were compared to the overall conversion obtained by DSC. Overall con version measured by DSC lies between styrene and polyester C=C bond co nversion obtained by FTIR. (C) 1998 SCI.
