Abstract:
Chain‐end‐functionalized polyethylenes (Cef‐PEs: PESSH (Cef 1 ), PESfurfuryl (Cef 2 ), PESNH 2 (Cef 4 ), PESNH 2 •HCl (Cef 5 ), PESCOONa (Cef 6 ), PESCHA(Cef 7 ), PESSO 3 Na (Cef 8 ), PESOH (Cef 9 ) and PESCOOH (Cef 10 )) are synthesized by thiol‐ene addition of vinyl‐terminated polyethylene (v‐PE) with 1,2‐ethanedithiol, furfurylmercaptan, cysteamine, cysteamine hydrochloride, sodium thioglycolate, L‐cysteine hydrochloride, sodium 2‐mercaptoethanesulfonate, mercaptoethanol, and thioglycolic acid, respectively. PEStNCO (Cef 3 ) is obtained by subsequent reaction of Cef 9 with anhydrous 4,4′‐MDI. Cef‐PE 1–8 are reported for the first time. The conversions of all the reactions are up to 95%–100%. All the Cef‐PEs are characterized by NMR, GPC, DSC, FT‐IR, and TGA. In the experiments, it is found that alkaline mercaptans and solvents are adverse to the thiol‐ene click reactions. image
