METHOD FOR STABILIZING PERFLUORODIOXOLANE COMPOUND, COMPOSITION INCLUDING PERFLUORODIOXOLANE COMPOUND, AND METHOD FOR MANUFACTURING PERFLUORODIOXOLANE COMPOUND POLYMER

Provided is a method of stabilizing a perfluorodioxolane compound, which includes having a quinone compound present in a composition containing a perfluorodioxolane compound, wherein the perfluorodioxolane compound is one or more perfluorodioxolane compounds selected from the group consisting of a perfluorodioxolane compound denoted by general formula (1) and a perfluorodioxolane compound denoted by general formula (2), and the quinone compound is one or more quinone compounds selected from the group consisting of a quinone compound denoted by general formula (3) and a quinone compound denoted by general formula (4).(In the formula, Rf1 and Rf2 each independently denote a fluorine atom or a perfluoroalkyl group having 1 to 6 carbon atoms, and an ether bond may be present in an arbitrary carbon-carbon bond in the perfluoroalkyl group. In addition, Rf1 and Rf2 may bond to each other to form a ring.)(In the formula, Rf3 and Rf4 each independently denote a fluorine atom or a perfluoroalkyl group having 1 to 6 carbon atoms, and an ether bond may be present in an arbitrary carbon-carbon bond in the perfluoroalkyl group.)(In the formula, R1 to R4 each independently denote a hydrogen atom, a fluorine atom or a chlorine atom.)(In the formula, R5 to R10 each independently denote a hydrogen atom, a fluorine atom or a chlorine atom.)
