The free-radical polymerization of styrene has been studied in the homogeneous phase of supercritical (sc) CO 2 at 80 8C and pressures between 200 and 1 500 bar. 2,29-Azobisisobutyronitrile is used as initiator and CBr 4 as chain-transfer agent. The polymerization is monitored by means of online FT-
The effects of pressure and of the composition of the CO2/ethanol mixed solvent in the critical region on the kinetics of the decomposition of 2,2'-azobis(isobutyronitrile) (AIBN) were studied at 333.15 K. The rate constants (kd) in the mixed solvent far from the critical point and in liquid n-hexan
