Among them, organic acids and solid acids are preferable from the viewpoint of production (from the viewpoint of easy availability and handleability), and hydrochloric acid or sulfuric acid is more preferable. These acid catalysts can be used alone as one kind or can be used in combination of two or more kinds. The amount of the acid catalyst used can be arbitrarily set according to, for example, the kind of the raw materials used and the catalyst used and moreover the reaction conditions, and it may be about 0.01 to 100 parts by mass based on 100 parts by mass of the entire reaction raw materials.


(5. Reaction Solvent)

During the polycondensation step, reaction raw materials may be subjected to reaction in a solvent. The solvent may be any solvent as long as it allows sufficient progress of reaction between the aniline and the aldehyde and/or the ketone, which are used as the reaction raw materials. Examples of the solvent include water, methanol, ethanol, propanol, butanol, tetrahydrofuran, dioxane, ethylene glycol dimethyl ether, ethylene glycol diethyl ether and a mixed solvent thereof. These solvents can be used alone as one kind or can be used in combination of two or more kinds.


The amount of the solvent used can be arbitrarily set according to, for example, the kind of the raw materials used and the catalyst used and moreover the reaction conditions, and it may be about 0 to 2000 parts by mass based on 100 parts by mass of the entire reaction raw materials.


The reaction temperature during the polycondensation reaction can be arbitrarily selected according to the reactivity of reaction raw materials, but it may be normally within the range of about 10 to 200° C. In order to obtain the (poly)amine compound according to the present embodiment, a higher reaction temperature is more preferable. Specifically, the range of 60 to 200° C. is preferable.


In the polycondensation step, the aniline, the aldehyde and/or the ketone, and the catalyst may be charged in one portion to allow reaction, or the aniline, the aldehyde and/or the ketone may be sequentially added dropwise in the presence of the catalyst to allow reaction. After the polycondensation reaction terminates, the obtained compound may be isolated by a publicly known method. For example, by elevating the temperature of the reaction vessel to 130 to 230° C. in order to remove unreacted raw materials and catalyst present in the system, and by removing volatile portions at about 1 to 50 mmHg, the (poly)amine compound can be obtained.


It is preferable to add the aniline in an amount of 1.0 mole or more and to add the acid catalyst in the range of 0.001 to 1 mole, based on 1.0 mole of the aldehyde and/or the ketone. In addition, it is preferable to conduct the reaction at normal pressure at a reaction temperature of 50 to 150° C. and for a reaction time of about 20 minutes to 100 hours.


After the reaction terminates, the (poly)amine compounds may be isolated by a publicly known method. In the isolation method, for example, the reaction solution is first concentrated, and pure water is added to precipitate the reaction product. Next, the precipitated reaction product is cooled to room temperature, and then separated by filtration. The solid matter obtained by the separation is further filtered and dried. The dried reaction product is separated and purified by column chromatography into the product and a byproduct. Furthermore, the reaction product separated and purified is subjected to solvent distillation, followed by filtration and drying, thereby obtaining the (poly)amine compound according to the present embodiment, which is the target compound.


After the polycondensation step, if the obtained (poly)amine compound has a substituent, the substituent may be eliminated by a publicly known method, thereby producing an unsubstituted (poly)amine compound.


[Substitution Step]

Hereinafter, the substitution step according to the present embodiment will be described.


In the substitution step according to the present embodiment, for example, a compound for introducing a crosslinkable group is used to substitute a hydrogen atom in a specific functional group with an acid crosslinkable group. Examples of the compound for introducing a crosslinkable group include allyl halides, acrylic acid, methacrylic acid, acrylic acid halides, methacrylic acid halides, vinylbenzyl halides and epihalohydrins, and these compounds may be synthesized by a publicly known synthetic method, or commercial products may be used therefor.


Hereinafter, the substitution method will be described with reference to a specific example. First, the compound for introducing the crosslinkable group is dissolved or suspended in an aprotic solvent (for example, acetone, tetrahydrofuran (THF), and propylene glycol monomethyl ether acetate). Next, an epihalohydrin (for example, epichlorohydrin and epibromohydrin) is added to the aprotic solvent. In the presence of an acid catalyst such as hydrochloric acid, reaction is allowed at normal pressure at a reaction temperature of 0 to 60° C. for a reaction time of 6 to 72 hours. The reaction solution is neutralized with a publicly known alkali compound, and distilled water is added to the reaction solution to precipitate a white solid. The separated white solid is washed with distilled water and dried, thereby obtaining a (poly)amine compound in which a hydrogen atom in the specific functional group has been substituted with the acid crosslinkable group.


Alternatively, a (poly)amine compound having a specific functional group is dissolved or suspended in an aprotic solvent. Next, an allyl halide (for example, allyl chloride and allyl bromide), acrylic acid, methacrylic acid, an acrylic acid halide (for example, acrylic acid chloride and acrylic acid bromide), a methacrylic acid halide (for example, methacrylic acid chloride and methacrylic acid bromide), or a vinylbenzyl halide (for example, vinylbenzyl chloride and vinylbenzyl bromide) are added to the solvent, and in the presence of an alkali catalyst (for example, sodium hydroxide, triethylamine and potassium carbonate), reaction is allowed at normal pressure at a reaction temperature of 0 to 110° C. for a reaction time of 6 to 72 hours. The reaction solution is neutralized with an acid such as hydrochloric acid, and distilled water is added to the reaction solution to precipitate a white solid. Next, the separated white solid is washed with distilled water and dried, thereby obtaining a (poly)amine compound in which a hydrogen atom in the specific functional group has been substituted with the acid crosslinkable group.


The timing at which the acid crosslinkable group is introduced may be before the polycondensation reaction between the aniline and the aldehyde and/or the ketone, or after the polycondensation reaction. In addition, it may also be after producing a resin, which will be mentioned later.


When the (poly)amine compound according to the present embodiment includes an acid crosslinkable group, the acid crosslinkable group is allowed to react in the presence of or in the absence of a radical, or an acid or an alkali, thereby improving refractive index, heat resistance, mechanical strength, permeability, and solubility in a coating solvent, or an acid or an alkali, or an organic solvent used for a developing solution.


Examples of the acid crosslinkable group include an allyl group, a (meth)acryloyl group, a vinyl group, an epoxy group, an alkoxymethyl group and a cyanato group.


[Cured Product]

The (poly)amine compound according to the present embodiment is used as a curing agent for curing a compound such as epoxy, urethane, urea and cyanate. As such, a cured product according to the present embodiment includes a cured product obtained by curing a curable compound with a curing agent, wherein the cured product has the (poly)amine compound according to the present embodiment. The curable compound normally refers to a compound that reacts with an amine-based compound, which is used as a curing agent, and is cured, and examples thereof include epoxy compounds, urethane compounds, urea compounds and cyanate compounds.

The resin according to the present embodiment has excellent structure-forming ability (for example, film-forming ability), heat resistance, transparency and refractive index due to the fact that it includes the monomer unit according to the present embodiment.


The resin according to the present embodiment may be composed of the monomer unit according to the present embodiment alone, may include another monomer unit that is copolymerizable with the (poly)amine compound, or may include a unit derived from a crosslinking compound.
