A method of preparing a cyclic monomer, comprising: forming a first mixture comprising a precursor compound, bis(pentafluorophenyl) carbonate, and a catalyst; wherein the precursor compound has a structure comprising a) two or more carbons, and b) two functional groups selected from the group consisting of primary amine, secondary amine, thiol group, hydroxyl group, and combinations thereof; and agitating the first mixture at a temperature effective to form a second mixture comprising the cyclic monomer, the cyclic monomer selected from the group consisting of a cyclic carbonate, a cyclic carbamate, a cyclic urea, a cyclic thiocarbonate, a cyclic thiocarbamate, and a cyclic dithiocarbonate.
制备环状单体的方法,包括:形成包括前体化合物、双(五氟苯基)碳酸酯和催化剂的第一混合物;其中前体化合物具有结构,包括a) 两个或更多碳,和b) 从一次胺、二次胺、硫醇基团、羟基团和它们的组合中选择的两个功能基团;并在有效温度下搅拌第一混合物,形成包括所述环状单体的第二混合物,所述环状单体选自环状碳酸酯、环状氨基甲酸酯、环状脲、环状硫代碳酸酯、环状硫代氨基甲酸酯和环状二硫代碳酸酯的组合。
