ABA and BAB triblock copolymers of vinylbenzyl chloride and styrene with low polydispersity and different block lengths and block length ratios were produced via reversible addition fragmentation chain transfer (RAFT) polymerization. The used RAFT agent butan‐1,4‐diyl‐bis(1‐phenylethyl)trithiocarbonate is a Z‐connected bis‐RAFT‐agent, that allows the synthesis of triblock copolymers in only two steps. The polyvinylbenzyl chloride blocks were quantitatively converted into polyamine blocks by reaction with diethyl amine. All the synthesized block copolymers are microphase separated polymers.
