Recently, the radical ring-opening polymerization of cyclic monomers has become one most important topics because it can impart degradability to vinyl polymers by introducing functional groups and heteroatoms into main chain through copolymerization with monomers. In this study, we investigated possibility sulfone compounds, including sulfolane sulfolene derivatives. First, reactions 2,5-dimethyl-3-sulfolene (DMS) were predicted using density theory (DFT) calculations, reaction product was actually examined after heating in presence a initiator. Next, synthesized polymerized 2-vinylsulfolane (2VS), which been reported undergo literature tried modify resulting containing unsaturated via post-polymerization ene–thiol additions. We also decomposition behavior polymer 2VS before hydrogenation. Furthermore, discussed reactivity 3-exomethylenesulfolane (3EMS), is expected exhibit similar 2VS, as well structure corresponding polymer.
