| 英文摘要 | Chain end functionalized polyolefins (Cef-POs) are of great importance in macromolecular design and polyolefin modifications. By utilizing self-induced chain transfer reactions (to beta-H, e. g.) or using chain transfer agents such as borane, phosphine and styrene (and its derivatives)/H-2 in olefin coordination polymerization, unsaturated bond and reactive group terminated polyolefins can be obtained, respectively. Successive chemical modification of chain-end group results in various Cef-POs. Given the status of "one polymer chain per catalyst" in living coordination polymerization of olefin, Cef-POs can also be obtained by endcapping living chains and/or applying functionalized living catalysts. The problem of low catalyst efficiency encountered in living coordination polymerization can be well solved by coordinative chain transfer polymerization (CCTP), a process involving rapid and reversible chain transfer reactions between the catalyst (active species) and the chain transfer agent (usually in the form of a main group metal alkyl). CCTP generates polyolefin capped by carbon-metal bond, which is highly reactive and can be modified into versatile terminal groups. In addition, living polymerization of Ylides, living anionic polymerization of butadiene and ring-opening metathesis polymerization of cycloolefine are alternative approaches to synthesize ( analogues of) Cef-PEs. The applications of Cef-POs, featured by transformation reaction from metallocene to other polymerization ( living anionic polymerization, "controlled/living" radical polymerization, ring-opening polymerization, etc.) and combination with click chemistry, include two main aspects: polymer modification and synthesis of topological polymer. |
