Abstract:
The modification of poly(1‐propyl‐3‐vinylimidazolium bromide) ( 3a ), poly(1‐hexyl‐3‐vinylimidazolium bromide) ( 3b ), poly(1‐isopropyl‐3‐vinylimidazolium bromide) ( 3c ), poly(1‐benzyl‐3‐vinylimidazolium bromide) ( 3d ), poly(1‐(1‐phenylethyl)‐3‐vinylimidazolium bromide) ( 3e ) has been conducted under microwave irradiation using N,N‐dimethylformamide as solvent and reagent. The products were formed by the decomposition of N,N‐dimethylformamide into dimethylamine and carbon monoxide. The proposed structure of the obtained copolymer contains mainly units of 1‐vinylimidazole and some units of amines, formamides, and alkenes. The reaction mechanism was established by use of model compounds 1‐propyl‐3‐methylimidazolium bromide ( 5a ), 1‐hexyl‐3‐methylimidazolium bromide ( 5b ), 1‐isopropyl‐3‐methylimidazolium bromide ( 5c ), 1‐benzyl‐3‐methylimidazolium bromide ( 5d ), 1‐(1‐phenylethyl)‐3‐methylimidazolium bromide ( 5e ), 1‐hexadecyl‐3‐methylimidazolium bromide ( 5f ).
