Vinyl-substituted 2,2'-bipyridine compounds of the formula ##STR1## and complexes thereof with metals or metal compounds other than alkali metals or alkaline earth metals, or alkali metal compounds, or alkaline earth metal compounds are described, R.sub.1 and R.sub.2 being as defined in patent claim 1 and the vinyl group being bonded in the 4-position or 6-position. The 2,2'-bipyridine compounds (I) are suitable for the preparation of complex-forming or complexed, crosslinked or uncrosslinked polymers. Complexed polymers, obtainable from these, are used, for example, as catalysts, in particular for transvinylation reactions. Uncomplexed polymers, which can be prepared from compounds (I), are suitable as metal ion scavengers in various applications.
本文描述了公式##STR1##的含有乙烯基取代的2,2'-联吡啶化合物及其与除碱金属、碱土金属或碱金属化合物、碱土金属化合物以外的金属或金属化合物的络合物。其中,R.sub.1和R.sub.2如专利要求1所定义,乙烯基团位于4-位或6-位。化合物(I)适用于制备形成配合物的交联或非交联聚合物。从这些聚合物中获得的配合物聚合物,例如用作催化剂,特别是用于转乙烯基化反应。可以从化合物(I)制备的非配合物聚合物适用于各种应用中的金属离子捕集剂。
