【Abstract】 The new ligand 1,2-dipiperidinoethane (DPE) was designed and synthesized, and applied to atom transfer radical polymerization of styrene and methyl methacrylate monomers. The characterization of “living”/controlled polymerization of the system with DPE as ligand for styrene and methyl methacrylate monomers was proved by the kinetic investigation. The polymerization reaction can carry out under the protection of high-purity nitrogen without the strict conditions such as freeze-vacuum-thaw process as usual.更多还原
