Abstract

Summary: Ligands suitable for atom transfer radical polymerization (ATRP) were prepared by the Michael addition of several acrylates (allyl, benzyl, butyl, 2‐ethylhexyl, and 3‐(dimethoxymethylsilyl)propyl acrylates) with tris(2‐aminoethyl)amine (TREN). These ligands, readily prepared from inexpensive precursors, were used for the preparation of catalyst complexes suitable for polymerization of (meth)acrylates and styrene, providing activity comparable to catalysts currently used for these monomers. Catalysts containing ligands with a dimethoxymethylsilyl substituent were examined for copper removal after the reaction mixture was contacted with silica gel.

## Abstract Tertiary amines were found to remarkably enhance the catalytic activity of ATRP catalysts CuBr/tris[(2‐pyridyl)methyl]amine and CuBr/tris[2‐(dimethylamino)ethylamine]. These two catalysts alone failed to polymerize MA, MMA, and styrene at reduced catalyst concentrations. With tertiary a
