Provided are a novel polymer having a sulfonic group, a sulfonic acid ester group, or a derivative thereof incorporated therein, a method of producing the polymer, and a novel compound suitable for producing the polymer. A polymer is characterized by containing a unit represented by the following formula (1):
wherein R1w and R1x are each independently a halogen atom or a hydrogen atom, R1y is a CH3 group or a hydrogen atom, and any one of R1a, R1b, and R1c is a sulfonate group represented by SO3R1f.
提供了一种含有磺酸基团、磺酸酯基团或其衍生物的新型聚合物,一种制备该聚合物的方法以及一种适用于制备该聚合物的新型化合物。所述聚合物的特征在于包含以下式(1)所表示的单元:其中,R1w和R1x各自独立地表示卤素原子或氢原子,R1y表示CH3基团或氢原子,R1a、R1b和R1c中的任意一个表示SO3R1f所表示的磺酸盐基团。
