New developments in reaction control of radical polymerization with direct stabilization of radical species

It was found that adding lithium salts such as LiN(SO_2CF_3)_2(LiNTf_2) to radical(co) polymerization of vinyl monomers such as N, N-dimethylacrylamide and methyl methacrylate increased both the polymer yields and molecular weights. Furthermore, lithium salts affected stereoregularities of the polymers obtained, depending on the structure of the monomers used. These results suggest stabilization of the propagating radical due to Li^+-radical interaction.
