| 中文摘要 | a series of functional polyethylenes have been simply and efficiently synthesized via the combination of regioselective ethylene/5-vinyl-2-norbornene (vnb) copolymerization using [phnc(cf3)chco(ph)]2ticl2 catalyst and following ultraviolet light initiated thiol-ene click reaction. on treatment of ethylene/vnb copolymer with different thiols including mercaptoethanol, 1-thioglycerol, methyl mercaptoacetate, methyl mercaptopropionate, 2-mercaptoethylamine, mercaptoacetic acid, and mercaptopropanoic acid, various polar groups have been successfully introduced into the polyethylene. except 2-mercaptoethylamine, the functionalizations are quite efficient with the degree of functionalization higher than 94%, which is independent of thiol structure and double bond content. the content of polar group in functional polyethylene can be tuned in a wide range of 030 mol %. gel permeation chromatography profiles indicate all functional polyethylenes that have very high molecular weights (160336 kg/mol) with homogeneous formation. besides, systematic investigation of the influence of vinyl type and thiol structure on reactivity has been also carried out. by treatment of mercaptoethanol with different copolymers (ethylene/vnb, ethylene/5-ethylidene-2-norbornene, and ethylene/dicyclopentadiene copolymer), the order of vinyl reactivity can be summarized as terminal > internal > cyclic double bond. for different thiols, the reactivity has the sequence of shch2cooh > shch2cooch3 > shch2ch2cooh > shch2ch2cooch3 > shch2ch(oh)ch2oh > shch2ch2oh > shch2ch2nh2, which is depended on the solubility and the electron-withdrawing inductive effect of polar group.
