    • The present invention relates to a process for synthesis of polymer compositions with reduced catalyst content, wherein ethylenically unsaturated monomers containing less than 0.5 wt % of ethylenically unsaturated monomers with at least one carboxylic group, sulfonic acid group and/or at least one phosphonic acid group relative to the total weight of the ethylenically unsaturated monomers are polymerized by means of initiators containing a transferable group of atoms and of one or more catalysts comprising at least one transition metal in the presence of ligands which can form a coordination compound with the metal catalyst or catalysts and, after the polymerization, the catalyst contained in the polymer is at least partly separated. For this purpose, the polymer composition is filtered, after the polymerization, in the presence of at least one filter aid which contains at least 0.5 wt %, relative to the total weight of the filter aid, of repeating units that contain at least one carboxylic acid group, sulfonic acid group and/or at least one phosphonic acid group.
    • 本发明涉及一种合成具有降低的催化剂含量的聚合物组合物的方法,其中含有少于0.5重量%的具有至少一个羧基,磺酸基和/或至少一个膦酸基的烯属不饱和单体的烯属不饱和单体 相对于烯键式不饱和单体的总重量,通过含有可转移原子基团的引发剂和包含至少一种过渡金属的一种或多种催化剂在可与金属催化剂形成配位化合物的配体存在下聚合,或 催化剂,并且在聚合之后,包含在聚合物中的催化剂至少部分地分离。 为此目的,在聚合后,在至少一种助滤剂的存在下过滤聚合物组合物,所述助滤剂相对于助滤剂的总重量含有至少0.5wt%的含有至少一个羧酸的重复单元 酸基,磺酸基和/或至少一个膦酸基。
