含氟嵌段共聚物联合收割机结合了含氟聚合物的独特性能和杂化大分子的有趣的自组装。本文介绍了用选择性氟化法制备标题化合物的方法以及氟掺杂对材料热力学的影响。我们强调了两个在我们的实验室，二氟卡宾和全氟烷基碘添加到聚二烯，允许不同的氟化基团的选择性和可调的模型嵌段共聚物的掺入计划。这种混合物改变了母体材料的物理性质，并导致组分不相容性发生有趣的变化。在确定嵌段共聚物在固态和溶液中的热力学，并最终利用嵌段共聚物产生新的，更高阶的结构的作用是我们的研究工作的核心。(C)John Wiley & Sons，Inc.
Fluorinated block copolymers combine the unique properties of fluoropolymers and the intriguing self-assembly of hybrid macromolecules. The preparation of the title molecules by selective fluorination procedures and the effect of fluorine incorporation on the material thermodynamics are presented. We highlight two fluorination schemes developed in our laboratory, difluorocarbene and perfluoroalkyliodide additions to polydienes, that allow for the selective and tunable incorporation of different fluorinated groups into model block copolymers. The fluorination changes the physical properties of the parent materials and leads to interesting changes in the component incompatibilities. The role of fluorination in determining block copolymer thermodynamics in both the solid state and in solution and in ultimately exploiting fluorination to produce novel, higher order structures is central to our research efforts.
