PROBLEM TO BE SOLVED: To provide a new material which promotes the polymerization of a monomer in a living-type free radical polymerization and to provide a polymerization process using it. SOLUTION: In this process, a mixture comprising at least one monomer, at least one free radical source, and a controlling agent having a thiocarbonyl group is polymerized and a post-treatment such as removing its thio part from the polymer and the like is carried out. The controlling agent is expressed as R<SP>1</SP>-D-C(=S)-N(R<SP>4</SP>)NR<SP>2</SP>R<SP>3</SP>(wherein R<SP>1</SP>is an alkyl, an aryl which can be substituted or the like; R<SP>2</SP>, R<SP>3</SP>and R<SP>4</SP>are H, a hydrocarbyl which can be substituted or the like; D is one of S, Se and Te). By this, a living-type free radical polymerization is enabled for various monomers. COPYRIGHT: (C)2006,JPO&NCIPI
