1-Dodecanthiol, carbon disulfide, potassium phosphate, 2-bromo-2-methylpropionic acid, and acetone were purchased from Sigma-Aldrich (St. Louis, MO) and used for the synthesis of 2-(dodecylthiocarbonothioylthio)-2-methylpropionic acid as a CTA for the RAFT copolymerization of acrylate monomers. The other CTA, 4-cyano-4-[(dodecylsulfanylthiocarbonyl)sulfanyl]pentanoic acid, was purchased from Sigma-Aldrich and used for the RAFT copolymerizations when the copolymerization mixture contained a methacrylate monomer.
