“…The design of sulfur-containing polymers from functional vinyl monomers is a promising platform for providing new functional materials and unique optical polymers [15,16]. Controlled radical polymerizations of sulfur-containing vinyl monomers, such as pyridyl disulfide ethyl methacrylate [17][18][19][20], disulfide-based di(meth)acrylates [21][22][23][24], and vinyl monomers with protected thiol groups [25][26][27][28], have been employed in the production of a variety of functional polymers with well-defined structures and highly ordered architectures.…”
