a)イソブテンをルイス酸触媒および場合により不活性希釈剤の存在下に、1000〜3000のMmax’を有する第1のイソブテンポリマーが得られるまで重合し、触媒を分離しかつ/または不活性化し、
b)第1のイソブテンポリマーから分子量112〜560を有するイソブテンオリゴマーを分離し、
c)これとは別にイソブテンをルイス酸触媒および不活性希釈剤の存在下にMmax3500〜8000を有する第2のイソブテンポリマーが得られるまで重合し、触媒を分離しかつ/または不活性化し、
d)第2のイソブテンポリマーから未反応のイソブテンおよび/または希釈剤を蒸留により分離し、蒸留の前または蒸留の過程で第2のイソブテンポリマーに工程b)からのイソブテンオリゴマーを添加する、
方法である。
EP−A−628575の実施例1によりポリイソブテンの製造を行った。使用したイソブテン供給流は次の組成に相当する:
− イソブタン <1質量%
− n−ブタン <1質量%
− 1−ブテン <1質量%
− トランス−2−ブテン <1質量%
− シス−2−ブテン <1質量%
− イソブテン 45質量%
− ヘキサン 54質量%
− ブタジエン <50ppm
− 水 <約2ppm
組込循環ポンプを備え、その環径が30mmでありその体積が1000mlであるループ型反応器の吸引側に前記供給流6000gを1時間かけて供給した。供給流1 lあたり三フッ化ホウ素を7.1ミリモルの量で、および2−ブタノールを三フッ化ホウ素に対して1.6倍モル量で供給する。反応器を反応媒体中の温度が−17℃であるように冷却した。反応器中での反応媒体の平均滞留時間は6.6分であった。反応取出し物を90℃の水2000g/hと強力に混合し、その際温度を35〜45℃に調節した。引き続き生じた両方の相を分離した。上方の相(以降“粗生成物”と呼ぶ)はポリイソブテン、未反応イソブテンおよびヘキサンからなる。
