    • The object of the present invention is to provide a vinyl monomer containing a superacidic ester group useful in the production of ionomers for polymer electrolyte fuel cells, and its production process. In addition, another object of the present invention is to provide a polymer produced from said vinyl monomer and its production process, as well as a process for producing a polymer containing a superacidic group from said polymer. The inventive vinyl monomer contains a haloalkyl ester group of a superacid, wherein the number of carbon atoms of the haloalkyl ester group is no more than 10, and the halogen in the haloalkyl group is chlorine and/or fluorine. A polymer containing said vinyl monomer as a repeating unit can be converted to a polymer containing a superacid group using at least one procedure of 1) heat treating at 50° C. to 350° C., and 2) contacting with a protic compound.
    • 本发明的目的是提供一种含有用于生产聚合物电解质燃料电池用离聚物的超酸酯基的乙烯基单体及其制造方法。 此外,本发明的另一个目的是提供由所述乙烯基单体制备的聚合物及其制备方法,以及从所述聚合物制备含有超酸基团的聚合物的方法。 本发明的乙烯基单体含有超酸的卤代烷基酯基,其中卤代烷基酯基的碳原子数不超过10,卤代烷基中的卤素是氯和/或氟。 含有所述乙烯基单体作为重复单元的聚合物可以使用至少一种如下步骤转化成含有超强酸基团的聚合物:1)在50℃至350℃下进行热处理,和2)与质子化合物接触。
