IMMOBILIZED 4,5-DICYANOIMIDAZOLE, PREPARATION METHOD THEREFOR, AND USE THEREOF

WIPO Patent Application WO/2024/066250

A1

The present invention provides an immobilized 4,5-dicyanoimidazole, a preparation method therefor, and use thereof. The immobilized 4,5-dicyanoimidazole is obtained by a free radical copolymerization reaction of a first comonomer, a second comonomer and a third comonomer. The first comonomer is divinyl benzene or ethylene glycol dimethacrylate. The second comonomer is styrene or methyl methacrylate. The third comonomer is 2-vinyl-4,5-dicyanoimidazole. The problem that it is difficult to separate 4,5-dicyanoimidazole from a reaction system after an activation coupling reaction in the prior art can be solved, and the present invention is suitable for the field of 4,5-dicyanoimidazole immobilization.
