The imidazole, acrylonitrile, bromooctane were used to synthesize a new cationic polymerizable ionic liquid surfactant named chlorinated-1-octyl-3-(4-butylacrylate-based) imidazole (PMOIH8). Using 2-chloropropylamide (MPC) as the initiator, Cu0 powder and tris-(2-dimethylamino ethyl) amine (Me6-TREN) as the catalyst, a new kind of copolymer acrylamide/acrylic ester was synthesized via single electron transfer living radical polymerization (SET-LRP) of acrylamide with PMOIH8. The resulting polymers were analyzed by FT-IR, MS and 1H NMR, and the results showed that the polymers were target products. The relative mol. mass and the distribution of the resulting polymer were determined by GPC. The relative mol. mass of polymers is within the range of 2 脳 103鈭?4 脳 103, and the relative mol. mass distribution is within the range of 1.21鈭?.75. Various factors which might affect the SET-LRP such as catalyst and initiator were discussed. The results showed that as the amount of catalyst reduced, the polymerization rate decreased and the polymerization rate constant (kpapp) reduced from 0.0168 min-1 to 0.0065 min-1, while the relative mol. mass distribution Mw/Mn increased from 1.25鈭?.71 to 1.32鈭?.75, and the initiator efficiency decreased, Ieff = 90.24%. As the amount of initiator increased, the relative mol. mass distribution of the resulting polymer was narrower with Mw/Mn reduced from 1.25鈭?.71 to 1.21鈭?.68, while the polymerization rate constant(kpapp) increased from 0.0168 min-1 to 0.0201 min-1, and the initiator efficiency increased, Ieff = 93.17%. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7HPLC of Formula: 21252-69-7).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. The pharmacophore of imidazole exists in bioactive compounds including amino acids, plant growth regulators and therapeutic agents.n increase of the alkyl chain length of the alcohols.
