摘要： The method consists in the polymerization of olefins with a prevailing content of 1-butene and cis- and trans-2-butenes in the mixture of hydrocarbons known as rafinate II, which is derived from the C₄-fractions after separation of 1,3-butadiene and isobutylene, under initiation with boron trifluoride (BF₃) or alkylaluminium chlorides with the general formulae R₂AlCl and RAlCl₂ (in which each R represents a C₁ to C₆-alkyl group) in the presence of hydrogen chloride (HCl), hydrogen fluoride (HF), or organic compounds with a reactive chlorine or fluorine bonded to a tertiary-, benzyl- or allyl-carbon atom, as coinitiators. The method according to the solution may be carried out in such a way, that rafinate II derived from the production of methyl tert-butyl ether or from the selective polymerization of isobutylene, in which 1-butene present in a concentration at least 20% is polymerized together with cis- and trans-2-butenes present in a concentration of at least 15%, at a temperature of +100°C to -70°C, to form to oily products with molar mass M n = 300 to 1200. Preferably the mixture derived as rafinate II from the production of methyl tert-butyl ether is first freed of methanol to the content lower than 300p ppm.

摘要翻译： 该方法包括在称为rafinate II的烃混合物中以1-丁烯和顺式 - 和反式 - 2-丁烯为主成分的烯烃的聚合反应，其分离出1,3-二丁烯， 丁二烯和异丁烯，在氯化氢（HCl），氟化氢（HF），氟化氢（HF）存在下，用三氟化硼（BF 3）或通式为R 2 AlCl和RACl 2的烷基氯化铝（其中每个R代表C1至C6-烷基） ）或具有与叔 - 苄基 - 或烯丙基 - 碳原子键合的反应性氯或氟的有机化合物作为共引发剂。 根据该溶液的方法可以以这样的方式进行，即从生产甲基叔丁基醚或由异丁烯的选择性聚合衍生的拉夫他II，其中以至少20％浓度存在的1-丁烯为 与-100至-70℃的温度下以至少15％的浓度存在的顺式和反式-2-丁烯一起聚合，以形成摩尔质量Mn = 300至1200的油状产物。优选地， 从生产甲基叔丁基醚得到的rafinate II衍生物的混合物首先从甲醇中除去低于300p ppm的含量。
