## Abstract The elevated temperatures required for the stable freeβradical polymerization (SFRP) process lead to thermal initiation of styrene via the classic Mayo mechanism. Studies have shown the utility of styrene thermal initiation in controlled autopolymerization processes. In addition, the th

## Abstract Bulk, freeβradical polymerization of styrene was carried out in the presence of a new tetrafunctional initiator (JWEB50, ATOFINA Chemicals, Inc.). The objective was to investigate the effect of initiator functionality on the free radical polymerization process. Size exclusion chromatogr
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-
