- the method for producing the vinyl polymer (I) of the present invention is not particularly limited.
- Bull-based polymers are generally produced by anionic polymerization or radical polymerization, but radical polymerization is preferred because of the versatility of the monomers and ease of control.
- radical polymerizations it is preferably produced by living radical polymerization or a radical polymerization using a chain transfer agent, and the former is particularly preferable.
- the radical polymerization method used in the method for synthesizing the vinyl polymer (I) of the present invention is a method in which a monomer having a specific functional group and a vinyl polymer are used by using an azo compound, a peroxide, or the like as a polymerization initiator. It can be categorized into the “general radical polymerization method” in which monomers are simply copolymerized, and the “controlled radical polymerization method” in which a specific functional group can be introduced at a controlled position such as the terminal.
- the "general radical polymerization method" is a simple method, a monomer having a specific functional group is introduced into the polymer only stochastically, so that a polymer with a high degree of functionalization is obtained. In this case, it is necessary to use a considerably large amount of this monomer. Conversely, if a small amount of the monomer is used, the proportion of the polymer into which the specific functional group is not introduced becomes large. In addition, since it is a free radical polymerization, there is a problem that only a polymer having a wide molecular weight distribution and a high viscosity can be obtained.
- the “controlled radical polymerization method” further includes a “chain transfer agent method” in which a vinyl polymer having a functional group at a terminal is obtained by performing polymerization using a chain transfer agent having a specific functional group. The terminal grows without termination reaction etc.
- the polymer can be classified into the “living radical polymerization method” in which a polymer having a molecular weight almost as designed can be obtained.
- the “chain transfer agent method” can obtain a polymer having a high functionalization rate, but requires a considerably large amount of a chain transfer agent having a specific functional group with respect to the initiator. There is a problem in the economy, including that. Further, as in the above-mentioned “general radical polymerization method”, there is a problem that only a polymer having a wide molecular weight distribution and a high viscosity can be obtained because it is a free radical polymerization.
- the “living radical polymerization method” is a radical polymerization that is difficult to control because the polymerization rate is high and the termination reaction is likely to occur due to force coupling between radicals. It is unlikely to occur and the molecular weight distribution is narrow (Mw / Mn is about 1.1 to 1.5). A polymer can be obtained, and the molecular weight can be freely controlled by the charging ratio of the monomer and the initiator.
- the ⁇ living radical polymerization method '' can provide a polymer having a narrow molecular weight distribution and a low viscosity, and can introduce a monomer having a specific functional group into almost any position of the polymer. It is more preferable as a method for producing a bullet-based polymer having the above specific functional group.
- living polymerization refers to polymerization in which the terminal is always active and the molecular chain grows.
- the polymerization in which the terminal is inactivated and the one in which the terminal is activated are activated. This includes pseudo-living polymerization that grows while in equilibrium.
- the definition in the present invention is also the latter.
- the "atom transfer radical polymerization method” for polymerizing vinyl monomers using an organic halide or a sulfonyl halide compound as an initiator and a transition metal complex as a catalyst includes the above-mentioned "living radical polymerization method".
- the production of vinyl polymers with specific functional groups is possible because of the high degree of freedom in designing initiators and catalysts that have halogens at the terminals that are relatively advantageous for functional group conversion reactions. The method is more preferable.
- This atom transfer radical polymerization method is described, for example, in Matyjaszewski et al., Journal of the American Chemical Society (J. Am. Chem. Soc.), 1995, Vol.

- a stable free radical such as a galvinoxyl (galvinoxyl) free radical may be used instead of the nitroxy free radical.
- the radical scavenger is used in combination with a radical generator. It is considered that the reaction product of the radical scavenger and the radical generator serves as a polymerization initiator, and the polymerization of the addition-polymerizable monomer proceeds.
- the combination ratio of the two is not particularly limited, but 0.1 to 10 mol of the radical generator is appropriate for 1 mol of the radical scavenger.
