Abstract: The paper briefly describes the general polymerization mechanism of reversible addition-fragmentation chain transfer (RAFT) polymerization and some common RAFT agents. The RAFT polymerization is compared with other two kinds of active controlled radical polymerizations [nitrogen oxide mediated free radical polymerization (NMP) and atom transfer radical polymerization (ATRP)]. The recent progress of synthesis of functional polyolefin block copolymers on the basis of RAFT polymerization is reviewed. Six kinds of combined methodologies based on RAFT polymerization aiming at the synthesis of functional polyolefin block copolymers are introduced：① Combination of olefin coordination polymerization and RAFT polymerization，②Combination of living anionic polymerization and RAFT polymerization，③Combination of cationic polymerization and RAFT polymerization，④Combination of Click chemistry and RAFT polymerization，⑤Combination of ring-opening polymerization and RAFT polymerization，⑥Combination of living polymerization of Ylides and RAFT polymerization. Finally，the prospect of the design and synthesis of functional polyolefin block copolymers via the strategy based on RAFT polymerization is presented.
