Three new morpholine‐based ligands were synthesized and used in the ATRP reactions of free polymers and polymers grown from the surface of a protein in aqueous media. The new ligands were designed in a way that decreased their Lewis basicity with each additional incorporation of a morpholine group (1, 2, and 3). The morpholine‐based ligands significantly slowed the polymerization rates and led to lower dispersities than Et 6 TREN. Increasing the control of aqueous ATRP correlated well with decreasing ligand basicity.
