    • To provide a fluoropolymer which has a high concentration of functional groups to provide adequate characteristics of the functional groups and which brings about no decrease of Tg. A fluoropolymer having monomer units formed by cyclopolymerization of a functional group-containing fluorinated diene represented by the formula (1): CFR1═CR2-Q-CR3═CHR4   (1) wherein each of R1 to R4 which are independent of one another, represents a hydrogen atom, a fluorine atom, an alkyl group having at most 8 carbon atoms, or an alicyclic hydrocarbon group, and at least one of them is an alicyclic hydrocarbon group, provided that hydrogen atoms in the alkyl group or the alicyclic hydrocarbon group may be substituted by a fluorine atom, an alkyl group or a fluoroalkyl group; and Q represents a bivalent organic group having a blocked acidic group capable of developing an acidic group by an acid or a group capable of being converted into such a blocked acidic group.
    • 提供具有高浓度官能团的含氟聚合物以提供官能团的足够特性,并且不会降低Tg。 具有由式(1)表示的含官能团的氟化二烯的环化聚合形成的单体单元的含氟聚合物:<?in-line-formula description =“In-line formula”end =“lead”→CFR < 1 -CR 2 -Q-CR 3 -RR 4(1)<?在线公式描述=“ 其中独立的R 1〜R 4中的每一个表示氢原子,氟原子, 具有至多8个碳原子的烷基或脂环族烃基,并且其中至少一个是脂环族烃基,条件是烷基或脂环族烃基中的氢原子可以被氟原子取代, 烷基或氟代烷基; Q表示可以通过酸或能够转化为这种封端的酸性基团的基团而能够形成酸性基团的封端酸性基团的二价有机基团。
