Abstract

In this article, we present the results of a study of the preparation of a cyclohexene oxide (CHO) mid‐chain functional macromonomer via ATRP of styrene (St) and epoxidation on work‐up with 3‐chloroperoxybenzoic acid. The ATRP initiator, BrCHBr, was synthesized by the condensation of 3‐cyclohexene‐1,1‐dimethanol with 2‐bromopropanoyl bromide. The ATRP of St with BrCHBr and Cu(I)/bpy yielded well‐defined polystyrene with a cyclohexene mid‐chain group (PStCHPSt). Epoxidation of the PStCHPSt was performed using 3‐chloroperoxybenzoic acid. GPC, IR and ^1^H NMR analyses revealed that a low polydispersity macromonomer of polystyrene with CHO functionality at the mid‐chain (PStCHOPSt) was obtained. The photoinduced cationic polymerization of PStCHOPSt yielded comb‐shaped and graft copolymers. magnified image

## Abstract A combination of ATRP and “click” chemistry is employed for efficient preparation of a novel well‐defined mid‐chain functional macrophotoinitiator of polystyrene. Bromo‐terminated polystyrene (PSt‐Br) is prepared by ATRP of styrene using a methyl‐2‐bromopropanoate initiator with CuBr/PM
