Design, synthesis and characterization of novel raft agents

[摘要] 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), nuclearmagnetic resonance spectroscopy (NMR) and ultraviolet spectroscopy (UV). The dithioesters werethen used as reversible addition-fragmentation chain transfer (RAFT) mediating agents in the bulkpolymerization of styrene, in order to observe differences in the kinetic behaviour of thepolymerizations and, as a result, the efficiencies of the dithioesters in mediating thepolymerizations.
