A polymer comprising mainly repeating units (1) and/or repeating units (2), containing optionally terminal groups (3) and/or repeating units (4), and having a reduced viscosity [ηsp/c] of 0.2 to 10.0 dl/g as measured in a 0.5 g/dl solution thereof in methylene chloride at 20°C; a resin coating fluid containing the polymer, a charge-transfer substance and a solvent; and an electrophotographic photoreceptor containing the polymer as a binder resin in a photosensitive layer, wherein Rf1 represents a group that is composed of at least carbon atoms and fluorine atoms and bonded directly to the two oxygen atoms of the carbonate linkage in the general formula (1) without any intervening arylene group; and Rf2 represents a group that is composed of at least carbon atoms and fluorine atoms and bonded directly to one of the oxygen atoms of the carbonate linkage in the general formula (3) without any intervening arylene group.
一种主要由重复单元(1)和/或重复单元(2)组成的聚合物,含有任选的末端基团(3)和/或重复单元(4),在 0.其中 Rf1 代表至少由碳原子和氟原子组成并直接与通式(1)中碳酸酯连接的两个氧原子键合的基团,而没有任何芳基介入;Rf2 代表一个至少由碳原子和氟原子组成的基团,直接与通式(3)中碳酸酯链节的一个氧原子键合,中间不含任何芳烯基。
