- the method for synthesizing the (meth) acrylic polymer in the present invention is controlled radical polymerization, and is not limited, but is preferably living radical polymerization, and more preferably atom transfer radical polymerization. These will be described below.
- the radical polymerization method is a general radical polymerization method in which a monomer having a specific functional group is simply copolymerized with a vinyl monomer using an azo compound, a peroxide compound, or the like as a polymerization initiator. Introduce a specific functional group at a controlled position, such as at the end It can be classified into the "controlled radical polymerization method".
- the “general radical polymerization method” is a simple method, a monomer having a specific functional group is stochastically not introduced into a force polymer, so that a polymer having a high functionalization rate will be obtained. In this case, it is necessary to use a considerably large amount of this monomer, and conversely, if the monomer is used in a small amount, there is a problem that the proportion of the polymer into which this specific functional group is not introduced becomes large. Further, since it is a free radical polymerization, there is a problem that a polymer having a wide molecular weight distribution and a high viscosity cannot be obtained.
- the “controlled radical polymerization method” further includes a “chain transfer agent method” in which a polymerization is performed using a chain transfer agent having a specific functional group to obtain a butyl polymer having a functional group at a terminal. It can be classified into the “living radical polymerization method”, in which a polymer having a molecular weight almost as designed can be obtained by growing the growing terminal without causing a termination reaction or the like.
- the “chain transfer agent method” can obtain a polymer having a high degree of functionalization, but requires a considerably large amount of a chain transfer agent having a specific functional group with respect to the initiator, and also includes processing. And there is an economic problem.
- general radical polymerization method since it is a free radical polymerization, it has a problem that a polymer having a wide molecular weight distribution and high viscosity cannot be obtained.
- the “living radical polymerization method” has a high polymerization rate.
- the termination reaction 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. Therefore, the "living radical polymerization method" can obtain 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 the above-mentioned bullet polymer having a specific functional group.
- living polymerization refers to polymerization in which the terminal is always active and the molecular chain grows, but in general, it is one in which the terminal is inactivated and one in which the terminal is activated. Pseudo-living polymerization that grows in a state of equilibrium is also included. The definition in the present invention is also the latter.
- the "atom transfer radical polymerization method” in which an organic halide or a sulfonyl halide compound is used as an initiator and a vinyl monomer is polymerized using a transition metal complex as a catalyst is the above-mentioned "living radical polymerization method”.
- (meth) acrylic acid with a specific functional group has halogens at the terminals that are relatively advantageous for the functional group conversion reaction, and has a high degree of freedom in designing initiators and catalysts. It is more preferable as a method for producing a '-based polymer.
- Such atom transfer radical polymerization methods include, for example, Matyjaszewski et al., J.
