Abstract

The ligand has an important role in atom transfer radical polymerization (ATRP) due to its complexation with the metal salt. The structure of the ligand strongly affects the catalyst activity and the control of the polymerization. Solubility of the ligand and its metal complexes in organic media is of particular importance to attain homogeneous polymerization conditions in ATRP. The rate of polymerization is also affected by the relative solubilities of the activating and the deactivating species of the catalyst. A series of alkylated linear amine ligands were synthesized in a simple and versatile reaction and their effect was investigated in copper-mediated ATRP. They show a homogeneous and relatively fast polymerization reaction compared to most other ATRP ligands
