摘要：

Direct synthesis of vinyl polymers functionalized with photo-labile diethylthiocarbamoylthiyl (S2CNEt2) groups was reviewed via three living polymerization procedures: normal atom-transfer radical polymerization (ATRP), reverse ATRP and photo ATRP. The S2CNEt2 group was transferred by mediating the dormant–active species equilibrium in the course of polymerization and eventually ω-terminating the resulting polymer chain. ATRP of methyl methacrylate (MMA) was successfully performed with a p-toluenesulfonyl chloride/Cu(S2CNEt2)/2,2′-bipyridine(bpy) or benzoyl peroxide (BPO)/Cu(S2CNEt2)/bpy initiation system. The oxidized complex, Cu(S2CNEt2)Cl/bpy, catalyzed the reverse ATRP of vinyl monomers initiated with BPO or 2,2′-azobisisobutyronitrile (AIBN), producing tailor-made polymers with ω-S2CNEt2 groups and a narrow molecular-weig
