Abstract
Summary: A highly active and versatile CuBr~2~/N,N,N′,N′‐tetra[(2‐pyridal)methyl]ethylenediamine (CuBr~2~/TPEN)‐tertiary amine catalyst system has been developed for atom transfer radical polymerization via activator‐generated‐by‐electron‐transfer (AGET ATRP). The catalyst mediates good control of the AGET ATRPs of methyl acrylate, methyl methacrylate, and styrene at 1 mol‐% catalyst relative to initiator. A mechanism study shows that tertiary amines such as triethylamine reduces the CuBr~2~/TPEN complex to CuBr/TPEN.
The GPC traces of PSt, PMA, and PMMA prepared by AGET ATRP at 1 mol‐% of catalyst relative to initiator are monomodal and have low polydispersities.
