For example, an acrylic resin that is inherently thermoplastic is required to have a function of photocuring or thermosetting after molding or coating.
熱可塑性アクリル樹脂が光硬化又は熱硬化する機能を備えるには、樹脂がその分子内に重合性二重結合を有した構造であること等が必要である。

また、特定のホスフィン化合物を触媒として用い、有機溶剤中で、カルボキシ基を有する共重合体のカルボキシ基にエポキシ基含有不飽和化合物を付加させる製造方法が知られている(特許文献2参照)。
In order for the thermoplastic acrylic resin to have a function of photocuring or thermosetting, it is necessary that the resin has a structure having a polymerizable double bond in the molecule.

Moreover, the manufacturing method which adds an epoxy-group-containing unsaturated compound to the carboxy group of the copolymer which has a carboxy group in an organic solvent using a specific phosphine compound as a catalyst is known (refer patent document 2).

このため、反応性アクリル樹脂を樹脂溶液として用いる場合には、その溶媒が、該アクリル樹脂の製造時に媒体として用いた有機溶剤に制限される、という問題がある。
また、反応性アクリル樹脂の用途が成型加工の場合には、前記アクリル樹脂溶液から有機溶剤を予め除去する操作を要する。

[工程(1)]
工程(1)では、単量体(a)と単量体(b)とを、水を媒体とした懸濁重合により共重合させてカルボキシ基含有アクリル樹脂を得る。
一例として、単量体(a)と、単量体(b)と、重合開始剤及び必要に応じてその他成分(以下「重合開始剤等」という)と、を水媒体に分散させて懸濁液を調製し、該懸濁液を加熱することで懸濁重合を行うことができる。
[Step (1)]
In the step (1), the monomer (a) and the monomer (b) are copolymerized by suspension polymerization using water as a medium to obtain a carboxy group-containing acrylic resin.
As an example, the monomer (a), the monomer (b), a polymerization initiator and, if necessary, other components (hereinafter referred to as “polymerization initiator”) are dispersed in an aqueous medium and suspended. Suspension polymerization can be performed by preparing a liquid and heating the suspension.
単量体(a)の配合量は、懸濁重合に用いる重合性単量体の総質量に対して20〜99.9質量%であることが好ましく、40〜99質量%であることがより好ましい。
単量体(a)の配合量を好ましい上限値以下とすることで、導入するカルボキシ基が過少となることなく共重合物を容易に得ることができる。一方、単量体(a)の配合量を好ましい下限値以上とすることで、導入するカルボキシ基が過多となることなく共重合物を容易に得ることができる。
単量体(b)の配合量は、懸濁重合に用いる重合性単量体の総質量に対して0.1〜50質量%であることが好ましく、1〜30質量%であることがより好ましい。
単量体(b)は水に溶解しやすい。このため、その配合量が50質量%を超えると、懸濁重合の際に、共重合物の粒子が凝集又は固化を生じやすい。一方、単量体(b)の配合量を好ましい下限値以上とすることで、得られる共重合物にカルボキシ基が充分に導入される。
尚、「懸濁重合に用いる重合性単量体」とは、単量体(a)、単量体(b)、これら以外の重合性単量体(後述の単量体(d))を包含する。
The blending amount of the monomer (a) is preferably 20 to 99.9% by mass and more preferably 40 to 99% by mass with respect to the total mass of the polymerizable monomer used for suspension polymerization. preferable.
By setting the blending amount of the monomer (a) to a preferable upper limit value or less, a copolymer can be easily obtained without introducing too few carboxy groups. On the other hand, by setting the blending amount of the monomer (a) to a preferable lower limit value or more, a copolymer can be easily obtained without introducing too many carboxy groups.
It is preferable that the compounding quantity of a monomer (b) is 0.1-50 mass% with respect to the gross mass of the polymerizable monomer used for suspension polymerization, and it is more preferable that it is 1-30 mass%. preferable.
The monomer (b) is easily dissolved in water. For this reason, if the blending amount exceeds 50% by mass, the particles of the copolymer tend to aggregate or solidify during suspension polymerization. On the other hand, a carboxy group is fully introduce | transduced into the copolymer obtained by making the compounding quantity of a monomer (b) more than a preferable lower limit.
The “polymerizable monomer used for suspension polymerization” refers to monomer (a), monomer (b), and other polymerizable monomers (monomer (d) described later). Includes.
単量体(a)と単量体(b)との混合比率は、「単量体(b)の配合量に対する、単量体(a)の配合量」の質量比が、1〜999であることが好ましく、2〜99であることがより好ましく、2〜20であることがさらに好ましい。
該質量比を好ましい上限値以下とすることで、導入するカルボキシ基が過少となることなく共重合物を容易に得ることができる。一方、該質量比を好ましい下限値以上とすることで、懸濁重合の際に、共重合物の粒子が凝集又は固化を生じにくい。加えて、導入するカルボキシ基が過多となることなく共重合物を容易に得ることができる。
The mixing ratio of the monomer (a) and the monomer (b) is such that the mass ratio of “the amount of monomer (a) to the amount of monomer (b)” is 1 to 999. It is preferable that it is 2 to 99, more preferably 2 to 20.
By setting the mass ratio to a preferable upper limit value or less, a copolymer can be easily obtained without introducing too few carboxy groups. On the other hand, when the mass ratio is set to a preferable lower limit value or more, the particles of the copolymer are less likely to aggregate or solidify during suspension polymerization. In addition, the copolymer can be easily obtained without excessive introduction of carboxy groups.
懸濁液中の水の含有量は、懸濁重合に用いる重合性単量体の総質量の1〜10倍に相当する質量であることが好ましい。
懸濁液の調製方法は、たとえば、水媒体に、単量体(a)と単量体(b)と重合開始剤等とを個別に加えて混合する方法;水媒体に、単量体(a)と単量体(b)と重合開始剤等との混合物を加えて混合する方法(後者)などが挙げられる。なかでも、懸濁液の分散安定性又は重合効率が良好なことから、後者の方法が好ましく、予め調製しておいた単量体(a)と単量体(b)と重合開始剤等との混合溶液を水媒体に加えて混合する方法が特に好ましい。
The water content in the suspension is preferably a mass corresponding to 1 to 10 times the total mass of the polymerizable monomers used for the suspension polymerization.
The method for preparing the suspension is, for example, a method in which the monomer (a), the monomer (b), the polymerization initiator and the like are separately added to the aqueous medium and mixed; the monomer ( Examples thereof include a method in which a mixture of a), the monomer (b) and a polymerization initiator is added and mixed (the latter). Among these, the latter method is preferable because the dispersion stability of the suspension or the polymerization efficiency is good. The monomer (a), the monomer (b), the polymerization initiator, and the like prepared in advance are preferable. Particularly preferred is a method in which the mixed solution is added to an aqueous medium and mixed.
単量体(a)と単量体(b)との懸濁重合を行う際の温度条件は、特に限定されないが、40〜100℃の範囲内とすることが好ましい。重合温度を40℃以上とすることで、比較的短時間で重合を行うことができ、重合温度を100℃以下とすることで、懸濁液の分散安定性を良好に維持しつつ重合を行いやすい。
かかる懸濁重合の間は、重合温度を、一定の温度に保ちながら重合を行ってもよく、連続的に又は段階的に温度を上昇させながら重合を行ってもよい。なかでも、重合効率が良好なことから、連続的に又は段階的に温度を上昇させながら重合を行うことが好ましい。
Although the temperature conditions at the time of performing suspension polymerization of a monomer (a) and a monomer (b) are not specifically limited, It is preferable to set it in the range of 40-100 degreeC. By setting the polymerization temperature to 40 ° C. or higher, polymerization can be performed in a relatively short time. By setting the polymerization temperature to 100 ° C. or lower, polymerization is performed while maintaining good dispersion stability of the suspension. Cheap.
During such suspension polymerization, the polymerization may be performed while maintaining the polymerization temperature at a constant temperature, or the polymerization may be performed while increasing the temperature continuously or stepwise. Among these, since the polymerization efficiency is good, it is preferable to carry out the polymerization while increasing the temperature continuously or stepwise.
単量体(a)と単量体(b)との懸濁重合を行う際の反応時間は、温度条件や重合スケール等を考慮して適宜決定すればよく、たとえば1〜20時間とすることが好ましい。
かかる懸濁重合を行う際、懸濁液の撹拌速度は、重合スケール等を考慮して適宜設定すればよく、たとえば撹拌翼の回転速度で20〜1000rpm程度とすることが好ましい。一例として実験室等のフラスコスケールの場合、懸濁液の撹拌速度は、撹拌翼の回転速度で200〜600rpm程度とすることが好ましい。

For example, the monomer (c) can be added to a mixed solution in which a carboxy group-containing acrylic resin and, if necessary, a dispersant and the like are dispersed in an aqueous medium, and the reaction can be performed by heating. Alternatively, the monomer (c) is added to the suspension after the suspension polymerization in the step (1) or to a mixed solution in which a dispersant or the like is added to the suspension as necessary, and heated.

[Infrared spectroscopy]
According to JIS K 0117, the presence or absence of polymerizable double bonds in the acrylic resin was confirmed.
Comparative sample used for infrared spectroscopy:
828 (Mitsubishi Chemical Corporation bisphenol A liquid epoxy resin).
-Methacrylic acid glycidyl ester (GMA).
-Ethylene glycol dimethacrylate.
A mixture of 828 / GMA = 200/30 (mass ratio).
A mixture of allyl glycidyl ether and 828 / allyl glycidyl ether = 200/40 (mass ratio).
図1は、828(上側)、及び、828とGMAとの混合物(下側)の赤外吸収スペクトルを示している。図2は、GMA(上側)、及び、エチレングリコールジメタクリル酸エステル(下側)の赤外吸収スペクトルを示している。
図2におけるGMA及びエチレングリコールジメタクリル酸エステルの赤外吸収スペクトルにおいて、1638cm−1付近に、重合性二重結合に由来するピークが認められる。したがって、実施例1〜4、6〜9では、赤外吸収スペクトルにおける1638cm−1付近のピークの有無を確認することにより、アクリル樹脂中の重合性二重結合の存在について評価した。
FIG. 1 shows infrared absorption spectra of 828 (upper side) and a mixture of 828 and GMA (lower side). FIG. 2 shows infrared absorption spectra of GMA (upper side) and ethylene glycol dimethacrylate (lower side).
In the infrared absorption spectra of GMA and ethylene glycol dimethacrylate in FIG. 2, a peak derived from a polymerizable double bond is observed in the vicinity of 1638 cm −1 . Therefore, in Examples 1-4 and 6-9, the presence of a polymerizable double bond in the acrylic resin was evaluated by confirming the presence or absence of a peak near 1638 cm −1 in the infrared absorption spectrum.
図3は、上から順に、実施例1、実施例2、比較例1でそれぞれ得られたアクリル樹脂の赤外吸収スペクトルを示している。図4は、上から順に、実施例3、実施例4、比較例2でそれぞれ得られたアクリル樹脂の赤外吸収スペクトルを示している。
図3及び図4において、GMAの配合部数に相応して1638cm−1付近にピークが認められる。すなわち、図3において、実施例1、実施例2については、1638cm−1付近にピークが認められ、比較例1についてはピークが認められなかった。図4において、実施例3、実施例4については、1638cm−1付近にピークが認められ、比較例2についてはピークが認められなかった。これより、実施例1〜4で得られたアクリル樹脂は重合性二重結合を有していること、が確認された。
加えて、実施例1〜4については、GMAの配合部数が多いほど、1638cm−1付近のピーク強度が高い。これより、GMAの配合部数が多いほど、アクリル樹脂中に重合性二重結合が多く存在していることが分かる。
FIG. 3 shows the infrared absorption spectra of the acrylic resins obtained in Example 1, Example 2, and Comparative Example 1 in order from the top. FIG. 4 shows the infrared absorption spectra of the acrylic resins obtained in Example 3, Example 4, and Comparative Example 2 in order from the top.
3 and 4, a peak is recognized in the vicinity of 1638 cm −1 corresponding to the number of blended parts of GMA. That is, in FIG. 3, for Example 1 and Example 2, a peak was recognized in the vicinity of 1638 cm −1 , and for Comparative Example 1, no peak was observed. In FIG. 4, for Example 3 and Example 4, a peak was observed near 1638 cm −1 , and for Comparative Example 2, no peak was observed. From this, it was confirmed that the acrylic resins obtained in Examples 1 to 4 have a polymerizable double bond.
In addition, about Examples 1-4, the peak intensity | strength of 1638 cm < -1 > vicinity is so high that there are many compounding parts of GMA. From this, it can be seen that the greater the number of GMA blended parts, the more polymerizable double bonds are present in the acrylic resin.
