Design, synthesis and characterization of novel raft agents

Thesis (MSc (Chemistry and Polymer Science))--University of Stellenbosch, 2005. / This thesis begins with the description of the preparation of thirteen dithioesters (of the form Z-
(C=S)-S-R) which were characterized via Fourier-transform infrared spectroscopy (FT-IR), nuclear
magnetic resonance spectroscopy (NMR) and ultraviolet spectroscopy (UV). The dithioesters were
then used as reversible addition-fragmentation chain transfer (RAFT) mediating agents in the bulk
polymerization of styrene, in order to observe differences in the kinetic behaviour of the
polymerizations and, as a result, the efficiencies of the dithioesters in mediating the
polymerizations.
