Catenated polymers are a class of polymer with mechanically interlocked rings without covalent bonding. This study focuses on the synthesis and characterization of catenated topologies using cyclic macromolecule with a disulfide bond. Utilizing ATRP, followed by azidation of bromine end-group and CuAAC click reaction, cyclic polystyrene with controlled molecular weight and distinct disulfide functionalized topological structure was synthesized. Characterization techniques, including multi-detector SEC, 1HNMR and MALDI-TOF were used to confirm the cyclic nature of the polymer. Catenated polymer was prepared through bulk thermal polymerization of the cyclic polymer. The incorporation of the dynamic disulfide bond in the cyclic polymer facilitated the formation of interlocking catenated structures, enhancing mechanical properties and thermal properties. This study demonstrates the formation of catenated structure and contributing to the advancements in the material science.
