Novel benzimidazolyl compounds which are basic compounds and have high polymerizability are disclosed. The basic compound of the present invention is prepared by reacting a vinylbenzaldehyde with an o-phenylenediamine compound, and can be used, for example, as a monomer for polymers. The benzimidazolylstyrene compounds are readily homopolymerized or copolymerized to provide linear homopolymers, linear copolymers or cross-linked copolymers having pendant benzimidazolylphenyl groups. These polymers have greater resistance to oxidation and chemicals than the homoiogues, and are useful as ion exchange resins, and as extractants of metals.
本发明公开了新型苯并咪唑基化合物,它们是碱性化合物,具有高聚合性。本发明的基本化合物是通过乙烯基苯甲醛与邻苯二胺化合物反应制备的,可用作聚合物的单体等。苯并咪唑苯乙烯化合物很容易均聚或共聚,从而得到具有悬垂苯并咪唑苯基基团的线性均聚物、线性共聚物或交联共聚物。与均聚物相比,这些聚合物具有更强的抗氧化性和耐化学性,可用作离子交换树脂和金属萃取剂。
