molar feed ratio of p‐cresol in relative to the repeat unit of the polymer of FPOx and 6F‐BPA in the range of 1–4, could be readily grafted onto the polymer by simply controlling the reaction temperature. FPOx‐based, versatile one‐pot synthesis of high molecular‐weight grafted polymers with well‐controlled structures and topologies were also demonstrated. © 2011 Wiley Periodicals, Inc. J Polym Sci
通过在不同反应条件下2,5-二五氟苯基-1,3,4-恶二唑(FPOx)与单官能对甲酚之间的模型反应,首次研究了全氟化芳基化合物的独特的阶梯式多功能性。四个明显不同的水平的反应性被发现为对位和邻位Ç FPOX的F,其可以很容易地通过将反应温度在室温范围到160触发℃。Ç 反应各级可以与亲核试剂(如苯酚)反应,定量的F; 通过控制反应条件,低级反应性CF不会干扰C的反应F具有较高的反应活性。已成功证明了FPOx的这种多级反应性在聚合物定量后聚合功能化中的应用。的化学计算量p甲酚,具有的摩尔进料比p相对于FPOX和6F-BPA的在1-4范围内的聚合物的重复单元甲酚,可以通过简单地控制被容易地接枝到聚合物上反应温度。还展示了基于FPOx的多功能一锅法合成具有良好控制的结构和拓扑的高分子量接枝聚合物。©2011 Wiley Periodicals,Inc.
