FREE RADICAL POLYMERIZATION PROCESS

Japanese Patent JP2005320549

A

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.

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 R1-D-C(=S)-N(R4)NR2R3 (wherein R1 is an alkyl, an aryl which can be substituted or the like; R2, R3 and R4 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.
