本発明において(A)成分の含窒素芳香族化合物と(B)成分のスルホン酸化合物の混合比は、目的とする芳香族ビニル化合物の重合抑制の程度に応じて適宜決定されるものであり、一律に決められないが、一般的には対象とする芳香族ビニル化合物に対し(A)成分の含窒素芳香族化合物と(B)成分のスルホン酸化合物を重量比で95:5〜5:95、好ましくは80:20〜20:80、より好ましくは70:30〜30:70の範囲で組み合わせて添加する。
(A)成分(含窒素芳香族化合物)
A−1:メチレンバイオレット(東京化成工業社製)
A−2:レソルフィン(東京化成工業社製)
A−3:クレシルバイオレット(Aldrich Chemical社製)
A−4:チオニン(Aldrich Chemical社製)
A−5:メチレンブルー(東京化成工業社製)
A−6:インジゴ
A−7:インジゴカーミン
A−8:キノキサリン
A−9:1−メチルキノキサリン
A−10:フェナジン
A−11:3−アミノ−7−ヒドロキシ−2−メチルフェナジン
A−12:テトラベンゾ[a、c、h、j]フェナジン
B−1:ドデシルベンゼンスルホン酸
B−2:ペンタデシルベンゼンスルホン酸
B−3:キシレンスルホン酸
B−4:クメンスルホン酸
B−5:p−トルエンスルホン酸
B−6:メタンスルホン酸
B−7:硫酸(98%)
DNBP:2,4−ジニトロ−6−sec−ブチルフェノール
H−TEMPO:4−ヒドロキシ−2,2,6,6−テトラメチルピペリジン−1−オキシル
還流冷却器を備えた4つ口セパラブルフラスコにスチレンモノマー100gを入れ、表1の重合抑制剤を所定量加え(各薬剤の配合割合は下に示した)、高純度窒素ガスを30分間吹き込んで溶存酸素を除いた。次いでこれを120℃に保持し、一定時間毎に内容物の一部を取り出してサンプリングし、液中のポリマー生成量(ppm)を測定した。サンプリング液の9倍容量のメタノールを加えてポリマーを液中に懸濁状態で析出させ、濾過してポリマー重量を秤量し、モノマー中のポリマー生成量%として求めた。なお、本実験を始める前に、スチレンモノマーをアルカリ洗浄してモノマー中に含まれる重合禁止剤(t−ブチルカテコール)を除き、水洗、乾燥した。得られた結果を表1に示す。
