Abstract: A polymeric catalyst was synthesized by co-polymerizing 4(5)- vinylimidazole and itaconic acid with trimethylpropanol trimethacrylate micro spheres. The catalyst obtained catalysed the transesterification process between p-nitrophenyl acetate and hexanol with maximal initial velocity(v(max)) of 4.73 0.47 μM min-1 mg-1, and turnover rate (k(cat)) of 8.67 min-1. Using p-nitrophenyl acetate as template, molecular imprinting process enhanced the v(max) of the polymeric catalyst 3-fold. Each imprinted site can be considered as a single molecular reaction vessel, and achieved a k(cat) of 169 min-1 towards the conversion of p-nitrophenyl acetate in hexanol.
