摘要: Techniques regarding the synthesis of one or more polymers through one or more ring-opening polymerizations conducted within a flow reactor and facilitated by one or more anionic catalysts are provided. For example, one or more embodiments can comprise a method, which can comprise functionalizing, via a post-polymerization reaction within a flow reactor, a chemical compound by covalently bonding a trimethylsilyl protected thiol to a pendent functional group of the chemical compound in a presence of a catalyst. The pendent functional group can comprise a perfluoroaryl group and a methylene group.
