共重合体(A)は、好ましくは構成単位(A-4)を含む。構成単位(A-4)は、下記式(4-1)または(4-2)で表される。
本発明の一実施形態である共重合体エマルジョンは、例えば、単量体(a-1)および単量体(a-2)を水とともに混合して製造すること、または有機溶剤中で重合後、界面活性剤と水を加えて乳化し、溶剤を留去して製造することができるが、乳化重合により製造することが好ましい。乳化重合による共重合体エマルジョンの製造は、公知の方法により行うことができる。例えば、予め単量体と水とを、好ましくは界面活性剤を用いて乳化分散させたモノマーエマルジョンを作製しておき、次いで、モノマーエマルジョンとは異なる容器で水、好ましくは水と界面活性剤の混合物を昇温した後に、これに先に作製したモノマーエマルジョンを滴下し、好ましくはラジカル重合開始剤を適宜に添加して乳化重合により製造することができる。反応温度や反応時間は、使用する単量体の種類や量に応じて適宜設定することができる。
共重合体エマルジョンの製造は、界面活性剤(C)の存在下で行うことが好ましい。界面活性剤としては特に限定されないが、一般的に用いられるノニオン性乳化剤、アニオン性乳化剤または反応性界面活性剤の1以上を使用することができる。界面活性剤(C)は、アニオン性乳化剤および反応性界面活性剤が好ましく、共重合体エマルジョン乾燥後の界面活性剤の表面へのブリードアウト抑制の理由から反応性界面活性剤がより好ましい。
連鎖移動剤(D)は共重合体(A)の分子量を調整するために必要に応じて用いることができる。連鎖移動剤(D)としては特に限定されないが、n-ヘキシルメルカプタン、n-オクチルメルカプタン、t-オクチルメルカプタン、n-ドデシルメルカプタン、t-ドデシルメルカプタン、n-ステアリルメルカプタン等のアルキルメルカプタン;2,4-ジフェニル-4-メチル-1-ペンテン、2,4-ジフェニル-4-メチル-2-ペンテン、ジメチルキサントゲンジサルファイド、ジイソプロピルキサントゲンジサルファイド等のキサントゲン化合物;ターピノレン、テトラメチルチウラムジスルフィド、テトラエチルチウラムジスルフィド、テトラメチルチウラムモノスルフィド等のチウラム系化合物;2,6-ジ-t-ブチル-4-メチルフェノール、スチレン化フェノール等のフェノール系化合物;アリルアルコール等のアリル化合物;ジクロルメタン、ジブロモメタン、四臭化炭素等のハロゲン化炭化水素化合物;α-ベンジルオキシスチレン、α-ベンジルオキシアクリロニトリル、α-ベンジルオキシアクリルアミド等のビニルエーテル;トリフェニルエタン、ペンタフェニルエタン、アクロレイン、メタアクロレイン、チオグリコール酸、チオリンゴ酸、チオグリコール酸2-エチルヘキシル等が挙げられる。これらを1種または2種以上用いてもよい。これらの連鎖移動剤の使用量は特に限定されないが、通常、共重合体(A)の固形分に対して0~5%使用される。
共重合体エマルジョンの製造は、重合開始剤(E)の存在下で行うことが好ましい。また、重合開始剤と還元剤を併用してレドックス系重合開始剤にして使用してもよい。還元剤としては、亜硫酸水素カリウム、重亜硫酸ナトリウム、亜硫酸カリウム、亜硫酸ナトリウム等を用いることができる。
本発明の一実施形態は、上記共重合体エマルジョンを含む、一液系熱硬化性樹脂組成物である。一液系熱硬化性樹脂組成物には、必要に応じて、顔料、染料、老化防止剤、増粘剤、フィラー等が含まれてもよい。一液系熱硬化性樹脂組成物は、塗料として好適に用いることができる。
本発明の一実施形態は、上記一液系熱硬化性樹脂組成物を硬化させた樹脂硬化膜(F)である。樹脂硬化膜(F)は、一液系熱硬化性樹脂組成物を、公知の方法により熱硬化させて得ることができる。樹脂硬化膜(F)は、構成単位(A-4)由来のカルボン酸またはヒドロキシ基が共重合体(A)内や共重合体(A)間で架橋することにより形成しやすくなると考えられる。熱硬化の際の温度は、110℃以上、好ましくは115℃以上であり、130℃未満好ましくは125℃以下である。
本発明の一実施形態は、上記共重合体エマルジョンと、後述するアクリルポリオール重合体エマルジョン(J)とを含む、二液系熱硬化性樹脂組成物である。共重合体エマルジョンと、アクリルポリオール重合体エマルジョン(J)は、それぞれ別々に調製した後混合して使用するか、または使用時まで別々の容器で保管する。二液系熱硬化性樹脂組成物は、塗料として好適に用いることができる。
アクリルポリオール重合体エマルジョン(J)は、公知のものを制限なく使用できるが、下記式(9)で表されるアクリルポリオール重合体を含むエマルジョンが好ましい。
本発明の一実施形態は、上記二液系熱硬化性樹脂組成物を硬化させた、樹脂硬化膜(M)である。樹脂硬化膜(M)は、調製された共重合体エマルジョンとアクリルポリオール重合体エマルジョン(J)とを混合したのち、公知の方法で熱硬化させて得ることができる。熱硬化の際の温度は、110℃以上、好ましくは115℃以上であり、130℃未満好ましくは125℃以下である。樹脂硬化膜(M)は、共重合体エマルジョン中の構成単位(A-2)と、アクリルポリオール重合体エマルジョン(J)中のアクリルポリオール重合体が架橋されることにより形成されると考えられる。
共重合体エマルジョン中の固形分は、共重合体エマルジョンをアルミ皿上に精秤後、熱処理(141℃で30分間)することにより乾燥させて固形分のみとし、乾燥前の質量と乾燥後の質量の差から算出した。
共重合体エマルジョン中の共重合体の数平均分子量(Mn)および重量平均分子量(Mw)は、共重合体エマルジョン約0.1gにTHF1.5mLを添加後に手で降り混ぜて溶解して、GPC(ゲルパーミエーションクロマトグラフィー法)により測定し、ポリスチレンで換算して算出した。
実施例または比較例で得られた樹脂乾燥膜または樹脂硬化膜をガラス基板からはがした後、8号ダンベル型に切り出した。切り出した各膜を引張圧縮試験機(オートグラフAGS-500NX、株式会社島津製作所製;引張速度:50mm/min、温度:23℃)を用いて引張試験を行った。引張試験はJIS-K7127―1999に準じた方法で行った。本試験により、室温における300%伸張時モジュラス(M300)、500%伸張時モジュラス(M500)、引張強さ(Tb)及び破断伸び(Eb)を測定した。樹脂硬化膜の各測定値から樹脂乾燥膜の各測定値を差し引いた差分(ΔTb、ΔEb、ΔM300、ΔM500)を算出した。
共重合体エマルジョンの調製直後、ならびに40℃で1週間、2週間および4週間保管した後の分子量を、上記測定方法によって測定した。
また、樹脂乾燥膜および樹脂硬化膜の調製直後、ならびに40℃で1週間、2週間および4週間保管した後の膜の引張強さ(Tb)、破断伸び(Eb)、300%伸張時モジュラス(M300)、500%伸張時モジュラス(M500)を、上記測定方法によって測定した。
