Synthesis of Star Polymer to Explore the Effect of Structure on Loading Efficiency

This thesis describes the extension of a valuable polymerization method, atom transfer radical polymerization (ATRP), to synthesis the star polymer economically and applied to aqueous dispersed media. Several parameters were tested during the synthesis of star polymers in solution condition, including the different arm lengths, different ratios of arms to cross-linkers, and different densities of cross-linked core in Chapter 1. In chapter 2, synthesis of star polymers in microemulsion system was explored, and various synthetic condition was deployed during this process. In particular, a new synthetic method, named as microemulsion, was recently developed by our group, and it shows high livingness and better control during the synthesis of polymers. At the same time, click reaction was used here to test the loading efficiency of star polymers.
