Description
により表されるカルボン酸塩を採用することにより、対応するカルボン酸よりもスコーチ時間を長くすることができるとともに、加硫温度範囲でのゴム組成物の加硫効率を高め、得られる加硫ゴムの耐熱老化性並びに室温及び高温での引張特性を向上できることを見出し、本発明を完成した。
により表される。
により表されるN−置換スクシンイミドチオ基含有カルボン酸と、Mg(OH)2 などの金属水酸化物、MgOなどの金属酸化物、又はMgBr2、MgCl2 などの金属ハロゲン化物とを反応させることによって上記一般式(I)の化合物を得ることができる。この反応の際、金属水酸化物又は金属酸化物を、N−置換スクシンイミドチオ基含有カルボン酸に対して等しいモル量で又は化学量論的に過剰な量で使用することが好ましい。反応条件は一般的に目的生成物とその原料の種類に応じて変わる。溶剤として、水、アルコール、例えばメタノール、エタノール、プロパノール、エチレングリコール、アセトン、メチルエチルケトン、N−メチル−2−ピロリドン、テトラヒドロフラン、N,N−ジメチルホルムアミド、トルエン、キシレン、ペンタン、ヘキサンなどを単独で又は組み合わせて使用することができる。好ましい溶剤は、反応生成物から分離が比較的容易であるという理由から、メタノール、エタノール及びプロパノールである。本反応の反応温度は、約0℃〜約130℃の範囲内であることが好ましい。0℃未満では、反応時間が長くなり、一方、130℃を超える反応温度では生成物の分解反応や望ましくない副反応が顕著になる可能性がある。
チオサリチル酸30.8g(0.20mol)とN−フェニルマレイミド34.6g(0.20mol)とをメチルエチルケトン300g中で、90℃で5時間反応させた。反応終了後、反応混合物を減圧下90℃で濃縮して、下記式:
上記のように得られた生成物を、1H−核磁気共鳴分光分析法(1H−NMR)及び質量分析法(MS)により分析した。得られた1H−NMRスペクトル及びMSスペクトルは以下のとおりである。
1H−NMRスペクトル(DMSO−d6):2.7ppm(CH2,1H),3.5ppm(CH2,1H),4.7ppm(S−CH,1H),7.2〜7.7ppm(Ph,9H).
FAB−MSスペクトル[M+H]+:677、日本電子データム(株)製JMS−BU20 GCメイトを使用して高速キセノン原子ビーム照射下で測定
以上の結果から、上記の生成物が下記式:
下記表1に示す配合成分を1.8リットルのバンバリーミキサーにより5分間混合して均一に分散させ、各実施例及び比較例の未加硫ゴム組成物を得た。得られた各実施例及び比較例の未加硫ゴム組成物を下記の各試験法により評価した。なお、比較例2で使用した化合物1のモル数と実施例1で使用した化合物2中に含まれるカルボン酸イオンのモル数がほぼ等しくなるように配合量を設定した。
(1)ムーニースコーチ時間:
上記のように得られた各未加硫ゴム組成物について、JIS K6300−1994に従って、L形ローターを使用し、予熱時間1分、試験温度125℃の条件で、ムーニー粘度を連続的に測定した。ムーニー粘度の最低値をVmとし、ムーニー粘度がVmから5ポイント上昇するまでのムーニースコーチ時間(分)を求めた。結果を表2に示す。ムーニースコーチ時間は、スコーチ(ゴム焼け)の指標であり、値が大きいほどより好ましい。
(2)圧縮永久歪:
得られた未加硫ゴム組成物を148℃で30分間又は180℃で10分間加硫し、円筒状の試験片(直径29mm×厚さ12.5mm)を作製した。JIS K6262に準じて円筒状の試験片を25%圧縮し、70℃で22時間放置した後の圧縮永久歪を測定した。値が小さいほどより好ましい。
(3)引張特性:
上記のように得られた各未加硫ゴム組成物について、148℃で30分間又は180℃で10分間加硫し、15cm×15cm×2mmの加硫シートを作成した。この加硫シートからJIS3号ダンベル形状の試験片を打ち抜いた。次いで、JIS K6251に従って、伸び100%時のモジュラス(M100)、300%時のモジュラス(M300)、破断応力(TB)及び破断時伸び(EB)を求め、それらの値を初期値とした。さらに、上記の各未加硫ゴム組成物の別の試料を148℃で30分間又は180℃で10分間加硫した後に、JIS K6257に従って、100℃で96時間老化した後のM100、M300、TB及びEBを測定した。また、上記の各未加硫ゴム組成物のさらに別の試料について、148℃で30分間加硫した後、100℃でJIS K6251に従ってM100、M300、TB及びEBを測定した。M100及びM300について、それらの上記初期値を基準として老化後の各値の変化率(%)を下記式:
[(老化後のM100)−(老化前のM100)]×100/(老化前のM100)
[(老化後のM300)−(老化前のM300)]×100/(老化前のM300)
に従って求めた。変化率の値が小さいほど、耐熱老化性に優れていることを表す。
