Summary: In this study, 3-, 4-, and 6-arm star poly(vinylbenzyl methylimidazolium chloride) were synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization with a core-first approach, resulting in uniform number and length of polymer arms. The effect of initial radical initiator concentration and number of functional groups per multifunctional RAFT agent on polymerization reaction kinetics was investigated. Increasing the initial radical initiator concentration led to faster monomer conversion, while decreasing the number of functional groups per multifunctional RAFT agent resulted in a decrease in the initial rate retardation in reaction kinetics. This work demonstrates a facile method for synthesizing ion-containing star polymers with uniform number and length of polymer arms, showing potential as a new material for electrochemical energy devices due to property enhancements associated with their star polymer architecture.
