例えば、
[1]下記一般式(1)
で示されるジ(メタ)アクリレート(1)と(以下、「ジ(メタ)アクリレート(1)」と称する)、下記一般式(2)
で示されるアルキル(メタ)アクリレート(2)(以下、「アルキル(メタ)アクリレート(2)」と称する)とからなる混合物を、有機リチウム化合物(L)、下記一般式(3)
で示される化学構造を分子中に含む三級有機アルミニウム化合物(A)(以下、アルミニウム化合物(A)と称する)並びにエーテルおよび三級ポリアミンからなる群から選ばれる少なくとも1種のルイス塩基(B)の存在下で、アニオン重合することを特徴とする(メタ)アクリル酸エステル系共重合体(X)(以下、共重合体(X)と称する)の製造方法;並びに
[2]前記混合物中のジ(メタ)アクリレート(1)とアルキル(メタ)アクリレート(2)とのモル比が、5:95〜90:10の範囲である、上記[1]の共重合体(X)の製造方法
を提供することにより達成される。
本発明の製造方法では、ジ(メタ)アクリレート(1)と、アルキル(メタ)アクリレート(2)とからなる混合物を、有機リチウム化合物(L)、アルミニウム化合物(A)、ルイス塩基(B)の存在下でアニオン重合する。ジ(メタ)アクリレート(1)においては、R2が結合している(メタ)アクリロイル基が選択的に重合され、R3およびR4が結合している炭素原子に結合する(メタ)アクリロイル基の重合は抑制されて、得られる共重合体(X)の側鎖に残留するので、かかる共重合体(X)は紫外線や電子線等を照射することで硬化させることができる。
で示される有機アルミニウム化合物(以下、アルミニウム化合物(A−1)と称する)または下記一般式(A−2)
で示される有機アルミニウム化合物(以下、アルミニウム化合物(A−2)と称する)を使用することが好ましく、アルミニウム化合物(A−1) を使用することがより好ましい。
以下の実施例等において、原料は常法により乾燥精製し、窒素にて脱気したものを使用し、移送および供給は窒素雰囲気下にて行った。
アニオン重合後のジ(メタ)アクリレート(1)およびアルキル(メタ)アクリレート(2)の消費率並びにジ(メタ)アクリレート(1)の側鎖官能基反応率は、反応液0.5mlを採取してメタノール0.5ml中に入れて混合後、該混合液から0.1mlを採取して、重クロロホルム0.5mlに溶解させて1H−NMR(ECX400(400MHz)JEOL製、測定温度=25℃、スキャン回数=16、緩和時間=4秒)を測定した結果から算出した。
ジ(メタ)アクリレート(1)の消費率C11(mol%)は、下記式により算出した。
C11=100(1−I11/I10)
ここで、I10、I11はそれぞれアニオン重合開始時およびアニオン重合停止時における、ジ(メタ)アクリレート(1)のR2における酸素原子に隣接する炭素原子に結合するプロトン由来のプロトンピークの積分値と、アニオン重合に用いたトルエンのベンゼン環由来のプロトンピークの積分値との比を示す。
アルキル(メタ)アクリレート(2)の消費率C21(mol%)は、下記式により算出した。
C21=100[1−{I21×(100−N×I11/I10)}/{I20×(100−N)}]
ここで、I10、I11はそれぞれ上記した比を示し、I20、I21はそれぞれアニオン重合開始時およびアニオン重合停止時における、互いに重なって観測されるジ(メタ)アクリレート(1)におけるR2が結合している(メタ)アクリロイル基のオレフィンに由来するプロトンピークとアルキル(メタ)アクリレート(2)のメタクリロイル基におけるオレフィンに由来するプロトンピークとの積分値の合計と、アニオン重合に用いたトルエンのベンゼン環由来のプロトンピークの積分値との比を示し、Nは反応開始時におけるジ(メタ)アクリレート(1)とアルキル(メタ)アクリレート(2)の総量に対するジ(メタ)アクリレート(1)のモル分率(mol%)を示す。
全体の消費率C(mol%)を、上記した方法で求めた消費率C11、C21および上記Nを用いて、下記式により算出した。
C={C11×N+C21×(100−N)}/100
なお、比較例においては、ジ(メタ)アクリレート(1)の消費率C11(mol%)
を消費率C(mol%)とした。
下記式により、ジ(メタ)アクリレート(1)の側鎖官能基反応率C31(mol%)
を算出した。
C31=100−100×I31/I30
ここでI30、I31はそれぞれアニオン重合開始時およびアニオン重合停止時における、R3およびR4が結合している炭素原子に結合するメタクロイル基のオレフィン由来のプロトンピークの積分値とアニオン重合に用いたトルエンのベンゼン環由来のプロトンピークの積分値との比を示す。
得られた共重合体(X)のGPC(ゲルパーミュエーションクロマトグラフィー、HLC-8220GPC(東ソー製)、カラム:TSK-gel SuperMultiporeHZ-M(東ソー製)(カラム径=4.6mm、カラム長=15cm)、測定条件:流速=0.35ml/min、温度=40℃、溶離液=テトラヒドロフラン)を測定し、標準ポリスチレン換算の数平均分子量分布(Mn)および分子量分布(Mw/Mn)を求めた。
内部を乾燥し、窒素置換した300mlのフラスコに、トルエン100ml、ルイス塩基(B)として1,1,4,7,10,10−ヘキサメチルトリエチレンテトラミン0.20ml(0.715mmol)、アルミニウム化合物(A)としてイソブチルビス(2,6−ジ−t−ブチル−4−メチルフェノキシ)アルミニウムの0.450mol/Lトルエン溶液を4.33ml加えて0℃に冷却した。これに有機リチウム化合物(L)としてsec−ブチルリチウムの1.30mol/Lシクロヘキサン溶液0.50ml(0.65mmol)を加えた。フラスコ内の混合液を激しく攪拌しながら、0℃で1,1−ジメチルプロパン−1,3−ジオールジメタクリレート3.09ml(13.0mmol)とメチルメタクリレート1.38ml(13.0mmol)との混合物4.47mlを加え、アニオン重合を開始した。0℃で攪拌を続けると、反応液は当初黄色の溶液となり、さらに窒素雰囲気下で攪拌を続けると30分後にほぼ無色となった。混合物の添加終了から120分後に、反応液をサンプリングして1,1−ジメチルプロパン−1,3−ジオールジメタクリレートおよびメチルメタクリレートの消費率Cおよび1,1−ジメチルプロパン−1,3−ジオールジメタクリレートの側鎖官能基反応率を測定すると共に、反応液中にメタノールを10.0ml加えることにより、アニオン重合を停止させた。得られた溶液を1リットルのヘキサン中に注ぎ、生成した共重合体(X)を沈殿させ、回収した。
イソブチルビス(2,6−ジ−t−ブチル−4−メチルフェノキシ)アルミニウムの0.450mol/Lトルエン溶液を7.22ml、1,1,4,7,10,10−ヘキサメチルトリエチレンテトラミンを0.35ml(1.30mmol)に変更した以外は、実施例1と同様にして共重合体(X)を得た。
イソブチルビス(2,6−ジ−t−ブチル−4−メチルフェノキシ)アルミニウムの0.450mol/Lトルエン溶液を3.18mlに変更し、混合物を1,1−ジメチルプロパン−1,3−ジオールジメタクリレート0.77mlとメチルメタクリレート1.04mlとの混合物(計1.81ml)に変更した以外は、実施例1と同様にして共重合体(X)を得た。

混合物を添加する前の反応器内温度およびアニオン重合する温度を−22℃とした以外は、実施例3と同様にして共重合体(X)を得た。
イソブチルビス(2,6−ジ−t−ブチル−4−メチルフェノキシ)アルミニウムの0.450mol/Lトルエン溶液を5.78mlに変更した以外は、実施例1と同様にして共重合体(X)を得た。

イソブチルビス(2,6−ジ−t−ブチル−4−メチルフェノキシ)アルミニウム0.450mol/Lのトルエン溶液を2.17mlに変更した以外は、実施例1と同様にしてアニオン重合を実施した。120分後にサンプリングしたが、単量体消費率が92%であり、単量体の残存が確認された。さらにアニオン重合を2時間継続したが、単量体消費率の上昇は殆ど見られなかったので、アニオン重合がほぼ停止していると判断して、アニオン重合開始から5時間後に実施例1と同様にアニオン重合を停止し、メタクリル酸エステル系重合体を得た。
1,1−ジメチルプロパン−1,3−ジオールジメタクリレートおよびメチルメタクリレートの混合物に代えて、1,1−ジメチルプロパン−1,3−ジオールジメタクリレート7.73mlのみを用いた以外は、実施例1と同様にしてアニオン重合を実施した。120分後にサンプリングしたが、単量体消費率が51%であり、単量体の残存が確認された。さらにアニオン重合を2時間継続したが、単量体消費率の上昇は殆ど見られなかったので、アニオン重合がほぼ停止していると判断して、アニオン重合開始から5時間後に実施例1と同様にアニオン重合を停止し、メタクリル酸エステル系重合体を得た。
1,1−ジメチルプロパン−1,3−ジオールジメタクリレートの量を6.19mlとし、該1,1−ジメチルプロパン−1,3−ジオールジメタクリレートを添加する前の反応器内温度およびアニオン重合する温度を−22℃とした以外は、比較例1と同様にしてアニオン重合を実施した。120分後にサンプリングしたが、単量体消費率が72%であり、単量体の残存が確認された。さらにアニオン重合を2時間継続したが、単量体消費率の上昇は殆ど見られなかったので、アニオン重合がほぼ停止していると判断して、アニオン重合開始から5時間後に実施例1と同様にアニオン重合を停止し、メタクリル酸エステル系重合体を得た。
