    • The invention relates to a method for producing mainly ethylenically unsaturated isobutene polymers, wherein the sum of proportions of molecules with a double bond in an α position and molecules with a double bond in a position β is increased to 75% mol by polymerising isobutene in a liquid phase in the presence of a diluted or dispersed catalyst complex which comprises (i) an electron donor and (ii) a compound of general formula (I) Ha Meb [MFx]c, wherein Me is a metal with oxidation state m, M is an element selected from elements of the groups 2, 3, 4, 5, 10, 11, 13, 14 or 15 of the periodic table according to the IUPAC notation of an element oxidation number n, a is an integer ≧1, b is an integer ≧0, x is an integer ≧2 and c is [(a+mb)/(x−n)]. The catalyst is preferably embodied in the form of HBF4 O(CH3)2. The inventive method makes it possible to obtain an isobutene polymer having a low fluorine-content even using technical C4 hydrocarbon portions as an isobutene source.
    • 本发明涉及一种主要生产烯键式不饱和异丁烯聚合物的方法,其中α位上具有双键的分子和位置上具有双键的分子的比例之和< 通过在稀释或分散的催化剂配合物存在下在液相中聚合异丁烯而增加至75%摩尔,其包括(i)电子给体和(ii)通式(I)的化合物Ha Meb [MF x] c, 其中Me是具有氧化态m的金属,M是根据元素氧化的IUPAC符号从元素周期表的第2,3,4,5,10,11,13,14或15族的元素中选出的元素 数n,a为整数≥1,b为整数≥0,x为整数≥2,c为[(a + mb)/(x-n)]。 催化剂优选以HBF 4 O(CH 3)2的形式实施。 本发明的方法使得即使使用工业C4烃部分作为异丁烯源,也可以获得具有低含氟量的异丁烯聚合物。
