摘要：

The effect of carboxylates on the Cu(I)-catalyzed `living' radical polymerization of butyl methacrylate (BMA) was investigated. The presence of thiophene carboxylate (Tc) salts resulted in higher rates compared to the acetate salts (Ac). Both the Tc systems and Ac systems showed the same rate which was indicated by the formation of similar active species. However, the use of carboxylic acid salts resulted to lower Mw/Mn. The lower polydispersity obtained by using carboxylic acid salts was due to the slow formation of the active cuprate species.
