In the synthesis of different block copolymers using reversible addition-fragmentation chain transfer (RAFT) polymerization, the RAFT agent 2-(Dodecylthiocarbonothioylthio)-propionic acid (DoPAT) was synthesized according to the literature. The reagents that were used for the synthesis of DoPAT were purchased from Sigma Aldrich. The RAFT agent, 4-cyano-4-(((dodecylthio)carbonothioyl)thio)pentanoic acid (97%, Boron Molecular) was used as received.
