摘要

<正>The novel cyclic trithiocarbonate was synthesized by dialkylation of trithiocarbonate anion with 2,2’-bis（bromomethyl）biphenyl in a two-phase system using an onium salt as a phase-transfer agent. Styrene polymerization was carried out in the presence of cyclic trithiocarbonate （CTTC）. CTTC undergoes ring opening-polymerization and the incorporated trithiocarbonate moiety derived from CTTC performs as the reversible addition-fragmentation chain transfer （RAFT） agent. Through this mechanism, multiblock polystyrenes containing various narrow polydispersity blocks can be prepared.
