Cyclic polymers reveal unique properties due to the absence of chain termini in contrast to other polymer topologies. Well-defined multi-cyclic polymers can be synthesized in general by combining atom transfer radical polymerization (ATRP), azidation and “click” chemistry. However, this synthesis method consists of multiple steps with labor purifications of end product in each step. Therefore, one-pot method could be considered for efficient synthesis of multi-cyclic polymers to eliminate a tedious multi-step synthesis method. In this study, all reactions to prepare cyclic polymers were carried out in one pot. The synthesized bicyclic polymer was characterized by 1H NMR, FT-IR spectroscopy and SEC. Consequently, the maximum purity of bicyclic polystyrene was determined by Gaussian multiple peak fitting and peak integration of SEC trace and was found to be about 48% under dilute condition. |
