  Conventionally, styrenic resins are widely used because they have a good balance between price, transparency, mechanical strength, and moldability. For example, home appliances, office equipment, household goods, food containers, packaging materials Used for toys. Various molding methods can be used. For example, the molding is performed by methods such as injection molding, extrusion molding, hollow molding, vacuum molding, and injection molding. In general, styrenic resins are mainly produced by thermal polymerization or radical polymerization using an initiator. The main production processes include a bulk polymerization method and a suspension polymerization method, but the bulk polymerization method has become mainstream because impurities such as a dispersant are difficult to be mixed and it is advantageous in terms of cost.

Patent Document 5 discloses a crosslinked polyester resin obtained by crosslinking at least a linear polyester resin and a polyester resin containing a trivalent or higher polyvalent carboxylic acid or a trivalent or higher polyhydric alcohol with a metal alkoxide or a metal chelate compound. A resin for an electrophotographic toner characterized in that it contains is described.

  As these polymerization methods, any known methods such as solution polymerization, suspension polymerization, emulsion polymerization, dispersion polymerization, precipitation polymerization, and bulk polymerization can be used, and are not particularly limited.

  Solution polymerization is one of the methods used for radical polymerization of a monomer having a vinyl group such as the styrene derivative used in the present invention. In this method, a monomer and an initiator are dissolved in a solvent in which the polymer to be produced is soluble, and polymerization is performed by heating. As the initiator, benzoyl peroxide or azobisisobutyronitrile soluble in a monomer or a solvent is used. The characteristics of solution polymerization are that the degree of polymerization and the polymerization rate are small compared to bulk polymerization, and the polymerization heat generated in the polymerization system is absorbed by the surrounding solvent, so that the polymerization temperature can be easily adjusted. Solution polymerization is extremely useful when used as a polymer solution as it is after completion of polymerization, but in order to take out the polymer as a solid, it is necessary to remove the solvent and recover the polymer.

  Bulk polymerization is one of the methods used for radical polymerization of a monomer having a vinyl group such as the styrene derivative used in the present invention. In this method, polymerization is carried out by heating only vinyl monomers as they are or adding a small amount of an initiator without using a solvent. As the initiator, benzoyl peroxide or azobisisobutyronitrile soluble in the monomer is used. Bulk polymerization is characterized by a high polymerization rate and a relatively pure polymer obtained in bulk. The problems of this reaction are that it is difficult to remove the heat of polymerization, so it is difficult to control the polymerization temperature, such as local heating, and the post-treatment is troublesome, such as solidifying the produced polymer and adhering to the container. There are drawbacks. Industrially, molding of polystyrene pellets by continuous bulk polymerization from styrene monomer, which is the styrene derivative used in the present invention, preparation of polymethylmethacrylate organic glass, curing of glass fiber reinforced unsaturated polyester, mold Bulk polymerization is used for polymerization in the inside-molding (cast polymerization).

  The precipitation polymerization is one of the methods used for radical polymerization of a monomer having a vinyl group such as the styrene derivative in the present invention. In this method, polymerization is carried out by heating using a solvent in which the monomer and the initiator are soluble, the polymer to be produced is not dissolved in the solvent, and hardly swells. As the initiator, benzoyl peroxide or azobisisobutyronitrile soluble in a monomer or a solvent is used. When polymerization starts and a polymer is formed, it is precipitated because it is insoluble in the solvent. The characteristics of precipitation polymerization are that polymerization starts and the precipitated polymer is essentially close to bulk polymerization, so the degree of polymerization and the polymerization rate are higher than those of solution polymerization, but the polymerization heat generated in the polymerization system is affected by the surrounding solvent. Therefore, it is relatively easy to adjust the polymerization temperature. Precipitation polymerization can be obtained after the completion of polymerization by isolation and drying to obtain a single polymer, without using a suspension stabilizer or emulsifier such as suspension polymerization or emulsion polymerization, and only the desired polymer is precipitated. Therefore, a pure polymer can be obtained.

  Suspension polymerization is one of the methods used for radical polymerization of a monomer having a vinyl group such as the styrene derivative in the present invention. When a monomer insoluble in the medium (mainly water) is vigorously stirred in the medium, the monomer is dispersed and suspended to form droplets having a size of 0.01 to 1 mm. Polymerization performed by adding an initiator (eg, benzoyl peroxide, azobisisobutyronitrile, etc.) soluble in the monomer to this is suspension polymerization. In addition, a polyaddition reaction such as polyurethane may be performed in a suspended state. In this polymerization method, it proceeds in the droplets of the monomer, and a particulate polymer is obtained. For example, when spherical polymerization is performed using vinyl acetate, styrene, methyl methacrylate, or the like as a monomer, spherical particles are obtained. In such a case, this is called pearl polymerization. The polymerization in the droplets is essentially the same as the bulk polymerization, and the polymerization rate and degree of polymerization are large. In the suspension polymerization, when the polymerization proceeds, the monomer droplets become a concentrated solution of the polymer using the monomer as a solvent, and the droplets easily adhere to each other. Therefore, it is necessary to carry out the polymerization with vigorous stirring so as to disperse well, and in order to stabilize the droplets, water-soluble polymers such as gelatin, starch, polyvinyl alcohol, carboxymethylcellulose, calcium carbonate, magnesium carbonate Add insoluble powder such as. In addition, the size of the polymer particles produced varies depending on the stirring speed. Further, since the heat of polymerization generated during the polymerization is removed by the surrounding medium, local overheating does not occur, and the temperature can be easily adjusted. In the suspension polymerization, a polymer having a high degree of polymerization is obtained, and the resulting polymer can be easily isolated, so that a polymer for molding material such as polystyrene, polymethyl methacrylate, polyvinyl acetate, polyvinyl chloride, etc. is obtained. For this purpose, it is widely used as an industrial production method. As the polymerization method used in the present application, solution polymerization, precipitation polymerization, and bulk polymerization are preferable.

  As a post-treatment step after the polymerization reaction, a known purification step or separation / extraction step can be performed. For example, it is preferable to provide a purification step such as separation using organic solvent or filtration, solvent purification, or reprecipitation. Moreover, bulk polymerization can be illustrated without adding a solvent.

  Various polymerization initiators such as peroxide polymerization initiators, azo polymerization initiators, and redox initiators can be used as appropriate as polymerization initiators that can be used for polymerizing each component of the monomer. Further, polymerization (natural polymerization) may be performed by heating without adding a polymerization initiator.

  The polymer obtained in these polymerization reaction steps can be converted into a metal complex or metal chloride to obtain an aluminum-containing copolymer resin. The metallization step is preferably performed by reacting the polymer obtained in the polymerization reaction step with a metallizing agent containing aluminum in a solvent under known conditions, so that at least a part of the unit A is made of aluminum. This is a step of producing an aluminum-containing copolymer resin containing a complexed or metallated copolymer.

  Specific examples of suitable metallating agents include aluminum chloride, aluminum sulfate, basic aluminum sulfate, aluminum acetate, basic aluminum acetate, aluminum nitrate, aluminum lactate, aluminum n-propoxide, aluminum isopropoxide, and t-butoxy.

  If the reaction product obtained in the metallization reaction in an organic solvent is dissolved in the solvent, disperse it in an appropriate amount of water or an organic solvent that is poorly soluble in the reaction product. Or an appropriate amount of the solvent is distilled off under reduced pressure to precipitate the reaction product. The precipitate can be collected by filtration, washed and dried. Further, when the reaction product is precipitated in the reaction solution, the precipitate can be directly collected by filtration, washed and dried. If the reaction product contains a large amount of impurities, its charge control function decreases, and therefore the reaction product can be used after solvent purification or reprecipitation purification.

  By being metallized by the above method, at least a part of the unit A constituting the polymer becomes a metal complexed or metallized copolymer, and the aluminum-containing copolymer resin of the present invention can be obtained.

When creating an electrostatic image developing toner or polymer compound containing this aluminum-containing copolymer resin by melt-kneading, by melt-kneading at or above the glass transition temperature at which the fluidity of the aluminum-containing copolymer resin increases, The compatibility with the binder resin becomes higher, the aluminum-containing copolymer resin can be uniformly dispersed, and the charging ability can be exhibited more efficiently.

  The aluminum-containing copolymer resin of the present invention has a number average molecular weight (Mn) of 3000 to 50000, a weight average molecular weight (Mw) of 4000 to 50000, and a weight average molecular weight (Mw) of a number average molecular weight (Mn). Mw / Mn, which is a standard for the molecular weight distribution divided by (1), is preferably 1 to 25. Further, the number average molecular weight (Mn) is in the range of 4000 to 50000, the weight average molecular weight (Mw) is in the range of 5000 to 40000, and the molecular weight distribution (Mw / Mn) is more preferably 1 to 20. If the value of Mw / Mn is close to 1.0, the dispersion is more monodispersed, the compatibility with the binder resin is higher, the aluminum-containing copolymer resin of the present invention can be uniformly dispersed, and the charging ability is improved. It can be exhibited more efficiently.

  The aluminum-containing copolymer resin of the present invention is preferably measured for exotherm and weight loss in the range of 200 ° C. to 450 ° C. in differential thermothermal gravimetric analysis (TG-DTA) measurement.

Further, since the heat resistance is increased, for example, the toner can be prevented from being decomposed during kneading with the binder resin, and a stable quality toner can be obtained. Furthermore, environmental stability, which is regarded as important in recent toner evaluation, is also improved. The charge control agent is a polymerization reaction step (preferably a polymerization reaction step using a polymerization initiator) in which a monomer containing a styrene derivative that becomes the unit A represented by the chemical formula (1) is polymerized.
