Summary

Star-like polymers were designed with α-D-glucose (GL) as the core and oligo(ethylene glycol) acrylate (OEGA) for the arms via an improved type of simplified electrochemically mediated atom transfer radical polymerization (seATRP) under preparative electrolysis conditions, utilizing only 40ppm of the catalyst system. The novelty of this work is to present the possibility of reducing the size of the platinum cathode in the reaction setup without significantly affecting the polymerization rate under constant potential/current conditions. This is an easier and cheaper solution than replacing it with other, expensive, non-platinum electrodes such as Au or Fe. The results obtained from nuclear magnetic resonance (1H NMR) and gel permeation chromatography (GPC) analyses clearly confirm the controlled nature of the electrochemically mediated polymerization of OEGA.
