“…An effective method for synthesizing sulfur-containing polymers is through the Michael addition of thiols and alkynes. 1–12 For example, functional hyperbranched polymers of prop-2-ynyl-3-mercaptopropanoate have been prepared by photo-initiated thiol–yne click polymerization under the assistance of the initiator of 2,2-dimethoxy-2-phenylacetophenone (DMPA), 13 and linear main chain polymers can be prepared by the UV-initiated click polymerizations of terminal monoynes with dithiols. 14 With applications in high performance polymer, 15–17 optical, 18,19 luminescent, 20 opto-electronic, 21 self-healing, 2,22 metal adsorption 23 and other fields, these polymers are in high demand.…”
