For this purpose, 4-bromomethyl benzoyl chloride was obtained using 4-methylbenzoyl chloride and N-bromosuccinimide. The mono functional bromomethyl benzoyl t-butyl peroxy ester (t-BuBP) was obtained by reaction of 4-bromomethyl benzoyl chloride with t-butyl hydroperoxide. Terminally brominated poly(methyl methacrylate) (PMMA-Br) was synthesized using t-BuBP and methyl methacrylate via free-radical polymerization. RAFT-macro agent was acquired by reaction of PMMA-Br and potassium ethyl xanthogenate. By reacting RAFT-macro agent and styrene, block copolymers were obtained. The primary parameters, for example concentration, and time that affect reaction were evaluated. The products were characterized by FT-IR, H-1-NMR, GPC, and TGA. The multi instruments studies of the obtained block copolymers show that the copolymers easily formed as a result of RAFT. Mn,GPC values of the copolymers were between 24,900 g.mol(-1) and 74,100 g.mol(-1).enAttribution-NonCommercial-ShareAlike 4.0 Internationalinfo:eu-repo/semantics/closedAccessReversible addition-fragmentation chain transfer polymerizationFree-radical polymerizationBlock copolymerRAFT-macro agentArticle27310.1007/s10965-020-2043-7Q2WOS:000520503500001Q2
