PROBLEM TO BE SOLVED: To provide a process of atom (or group) transfer radical polymerization for the synthesis of novel homopolymer or a block or graft copolymer, optionally containing at least one polar group, having a well defined molecular structure and a narrow polydispersity index. SOLUTION: In the present process of radical polymerization, a radical polymerization is performed in the presence of an initiating system comprising (i) an initiator having a radically transferrable atom or group, (ii) a transition metal compound, and (iii) a ligand. In addition, the process of radical polymerization is directed to the synthesis of a macromolecule having at least two halogen groups which can be used as a macroinitiator component to subsequently form a block or graft copolymer by an atom or group transfer radical polymerization process.
