Vinylphenyl benzimidazole derivatives, their polymers, their preparation and use.

摘要

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.
