Abstract: To provide a monomer composition in which the solubility of the polymerization inhibitor in the cyclic monomer is good, the stability of the cyclic monomer during storage is good, and the cyclic monomer and the polymerization inhibitor are easily separated by distillation; and a method for producing a high molecular weight fluorinated polymer from the monomer composition.
A monomer composition which comprises a specific cyclic monomer and a polymerization inhibitor, wherein the polymerization inhibitor is a polymerization inhibitor which satisfies (a) it is a 6-membered unsaturated cyclic hydrocarbon having from 1 to 4 substituents, (b) it has, as the substituent, at least one type selected from the group consisting of a t-butyl group, a methyl group, an isopropenyl group, an oxo group and a hydroxy group, (c) in a case where it has an oxo group as one type of the substituent, it has, as the substituent other than the oxo group, either one or both of a t-butyl group and a methyl group, and (d) in a case where it has a hydroxy group as the substituent, the number of the hydroxy group is only one.
