A modified ATRP process was developed by making use of ULIS. For this purpose a wide variety of ligand-initiator systems were synthesized and characterized. Use of ULIS in ATRP process in place of conventional ligands and initiators allowed the polymerization to proceed with low quantities of copper salt, 10's of ppm orlower. The effect of concentration of copper salt on polymerization was studied. The lowering concentration did not affect the rate of polymerization. However, loss of control was observed. Even then, the polymerization did not lose its living characteristics.
