  自由基聚合中的硫代羰基硫基化合物（SC（Z）S-R）可逆加成-断裂链转移（RAFT聚合）。Z活化基团的作用

  An electrophoretic particle includes a base particle (particle) that includes a first functional group, and a first compound and a second compound bonded to the base particle. The first compound is a polymer that includes a dispersion portion derived from a first monomer that contributes to dispersibility and a bonding portion derived from a second monomer including a second functional group having reactivity to the first functional group, and is connected to the base particle at the bonding portion. The second compound has a lower molecular weight than the first compound, includes a non-polar group and the second functional group, and is connected to the base particle at the second functional group.

  Radical cascade reactions enabling sequence-controlled ring-closing polymerization and ring-opening polymerization for the controlled synthesis of polymers with complex main-chain structures are provided. Facile syntheses leading to low-strain macrocyclic monomers consisting of the ring-opening triggers and extended main-chain structures are also provided. The present disclosure further provides methods for excellent control over polymer molecular weights and molecular weight distributions and high chain-end fidelity allows for the preparation of polymeric systems with well-defined architectures. Further provided are the general nature of the radical cascade-triggered transformations in polymer chemistry, and its application to the synthesis of polymers with diverse main-chain structural motifs with tailored functions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
