In the past 80 years, fluoropolymers have found broad applications in both industrial and academic settings, owing to their unique physicochemical properties. Copolymerizations of fluoroalkene feedstocks present an important avenue to obtain high-performance materials by merging intrinsic attributes of fluorocarbons and great versatility of comonomers. Recently, while massive investigations have disclosed the great potentials of precisely synthesized polymers, researchers have made considerable efforts to approach well-defined fluorinated copolymers. This minireview discusses challenges in controlled radical copolymerizations (CRCPs) of fluoroalkenes and provides a concise perspective on recent progress in CRCPs of fluoroalkenes (e.g., tetrafluoroethylene, chlorotrifluoroethylene, hexafluoropropene, perfluoroalkyl vinyl ethers) with non-fluorinated vinyl comonomers, which have enabled on-demand preparations of various main-chain fluoropolymers with predefined molar masses, low dispersities, as well as regulable chemical compositions and sequences. The synthetic advantages of CRCPs will promote controlled and facile access to customized fluoropolymers for high-tech applications such as batteries, coatings and so on.
在过去的80年里，含氟聚合物因其独特的物理化学性质在工业和学术领域都有广泛应用。氟代烯烃原料的共聚反应是通过融合碳氟化合物的固有特性和共聚单体的多功能性来获得高性能材料的重要途径。近年来，虽然大量研究揭示了精确合成聚合物的巨大潜力，但研究人员也付出了巨大努力来制备结构明确的含氟共聚物。本综述讨论了氟代烯烃的可控自由基共聚（CRCP）中的挑战，并简要介绍了氟代烯烃（如四氟乙烯、三氟氯乙烯、六氟丙烯、全氟烷基乙烯基醚）与非氟代乙烯基共聚单体的CRCP的最新进展，这些进展使得按需制备具有预定义摩尔质量、低分散度以及可调节化学组成和序列的各种主链含氟聚合物成为可能。CRCP的合成优势将促进定制含氟聚合物的可控且简便的制备，以用于电池、涂料等高科技应用。
