Abstract
AbstractCopolymerizations of 4(5)‐vinylimidazole (1) and γ‐vinyl‐γ‐butyrolactone (2) initiated by 2,2′‐azoisobutyronitrile or benzoyl peroxide were carried out. The initiators did not affect the radical reactivity ratio (r). In addition, the reactivity ratio was not influenced by methanol as solvent. The following ratios were obtained r1 = 20,0 ± 0,8 and r2 = 0,030 ± 0,002.The catalytic activity of the copolymers in the hydrolyses of p‐nitrophenyl acetate (4) and 3‐acetoxy‐N,N,N‐trimethylanilinium iodide (5) at pH = 8,0 was found to be more than twice as high as that of a random terpolymer containing imidazole, carboxylic acid, and hydroxy moieties.
