- the "general radical polymerization method” is a simple method, but in this method, a monomer having a specific functional group is introduced into the polymer only stochastically! In order to obtain a polymer, it is necessary to use a considerably large amount of this monomer. Conversely, when a small amount of the monomer is used, there is a problem that the proportion of the polymer into which this specific functional group is not introduced becomes large. In addition, there is a problem in that only a polymer having a wide molecular weight distribution and a high viscosity can be obtained because of free radical polymerization.

Therefore, the method for producing the vinyl polymer having the specific functional group is more preferable.
- living polymerization refers to polymerization in which the terminal is always active and the molecular chain grows. Pseudo-living polymerization in which the polymer grows while in equilibrium is also included. The definition in the present invention is also the latter.
