摘要： A method of producing a fluorine-containing compound is a method of producing a compound (30) having partial structure (3) by an insertion reaction of compound (20) into compound (10) that has partial structure (1), in the presence of an ionic catalyst formed from a specific monovalent anion and a counter cation. In the formulas, * represents a bonding site, and X1 and R1 to R4 each independently represents a hydrogen atom, a fluorine atom, a chlorine atom, or an organic group having a carbon number of 1 to 20 which may have a substituent.

摘要： A fluorine-containing polymer has a fluorine content of 50% by mass or more, a degree of unsaturation of 0.1 mEq/g or more, and a glass transition temperature of −20° C. or higher, and the relationship between the maximum value E*1 of the complex elastic modulus in the range of from −50° C. to (glass transition temperature−10° C.) and the minimum value E*2 of the complex elastic modulus in the range of from (glass transition temperature+10° C.) to 250° C. satisfies the following inequality: E*2/E*1≤0.01.
