Abstract

The free-radical polymerization of styrene has been studied in CO₂/ethanol mixed supercritical fluid. Depending on the experimental conditions, yields varied from low to fairly good (around 60%). The polymers exhibited molar masses ranging from 5000 to 26000 g/mol. The results obtained were compared with those generated in the presence of mesitylene or pure ethanol used as solvent. In particular, it was observed that the thermal polymerization of styrene in the supercritical fluids or in ethanol was somewhat inhibited as compared to that occurring in mesitylene. Indeed, almost no thermal polymerization could be observed in these conditions.
