摘要： An advantageous process for producing an unsaturated telechelic isobutylene polymer wherein the formed polymer is isolated in a nonaqueous system to prevent the occurrence of an effluent containing the solvent dissolved therein. The process comprises: a method of isolating an isobutylene polymer in a nonaqueous cationic polymerization reaction using a catalyst represented by the general formula (I): MXn (wherein M represents a metal atom; n represents an integer of 2 to 6; and Xs represent each independently halogen or a monovalent hydrocarbon group), characterized by conducting catalyst ligand exchange after the polymerization and removing the component containing the atom M of the above formula (I); a method of isolating an isobutylene polymer in a nonaqueous cationic polymerization reaction using a catalyst represented by the above formula (I), characterized by forming a telechelic isobutylene polymer and removing the catalyst by using an adsorbent capable of adsorbing acids; and a method of isolating an isobutylene polymer in a nonaqueous cationic polymerization reaction using a catalyst represented by the above formula (I), characterized by adding a compound represented by the following general formula (II): Q(OR)m, (wherein Q represents a group Ia, IIa, IIIb or IVa metal atom of the Periodic Table; m represents an integer of 1 to 6; and R represents hydrogen or a monovalent organic group, provided when m is 2 or more, mR's may be the same or different from each other) after the polymerization to eliminate the HC1 molecule from the polymer chain end and conduct catalyst ligand exchange to thereby form an unsaturated telechelic isobutylene polymer, and removing the component containing the atom M of the above formula (I).
摘要翻译：制备不饱和遥爪异丁烯聚合物的有利方法，其中形成的聚合物在非水系统中分离以防止含有溶剂溶解的流出物的出现。该方法包括：使用由通式（I）表示的催化剂在非水阳离子聚合反应中分离异丁烯聚合物的方法：MXn（其中M表示金属原子; n表示2至6的整数; X表示各自独立地为卤素或一价烃基），其特征在于在聚合后进行催化剂配体交换并除去含有上述式（I）的原子M的组分; 使用由上述式（I）表示的催化剂在非水阳离子聚合反应中分离异丁烯聚合物的方法，其特征在于，形成遥爪异丁烯聚合物并通过使用能够吸附酸的吸附剂除去催化剂; 以及使用上述式（I）表示的催化剂在非水阳离子聚合反应中分离异丁烯聚合物的方法，其特征在于，添加下述通式（II）表示的化合物：Q（OR）m，（其中Q 表示周期表中的Ia，IIa，IIIb或IVa族金属原子; m表示1至6的整数; R表示氢或一价有机基团，当m为2或更大时，mR可以相同或者彼此不同），从聚合物链端除去HC1分子，进行催化剂配体交换，从而形成不饱和的遥爪异丁烯聚合物，并除去含有上述式（I）的原子M的成分。
