ATRP of 2‐( N,N ‐dimethylamino)ethyl acrylate (DMAEA) was investigated using CuBr or CuCl with different multidentate ligands. The catalyst was found active for DMAEA polymerization when ligated with tris[2‐( N,N ‐dimethylamino)ethyl]amine. Good control over molecular weight was achieved, but quaternization of the terminal monomeric/polymeric tertiary amine by the CBr group of polyDMAEA caused chain termination. Using a chloride‐based system helped to suppress chain termination. Amphiphilic poly(methyl acrylate)‐ block ‐polyDMAEA was synthesized using polyMA as a macroinitiator.Molecular weights and polydispersities of polyDMAEA versus DMAEA conversion for different catalyst systems.
