Polystyrene (PSt) with end-terminal bromine (Br-PSt-Br) was synthesized by the atom transfer radical polymerization of styrene with the difunctional initiator 1,2-bis(2ะ-bromobutyryloxy)ethane in combination with CuBr and bipyridine. The Br-PSt-Br reacted with silver perchlorate at ฯช78 ยฐC, and the r

Styrene underwent the ATRP process using an asymmetric difunctional initiator, 2-hydroxylethyl 2ะ-bromobutyrate in combination with CuBr and 2,2ะ-bipyridine (bpy). Polystyrene with hydroxyl and bromine groups at each end of the polymer (HO-PSt-Br) was obtained, and used as a chain-transfer agent in
