METHOD FOR PRODUCING FLUORINATED POLYETHER

WIPO Patent Application WO/2023/058754

A1

[Problem] To provide a method for producing, at a high yield, a fluorinated polyether having a number average molecular weight matching the theoretical number average molecular weight calculated from the number average molecular weight of a polyether compound serving as raw material. [Solution] A method for producing a fluorinated polyether characterized by including a step (1) for introducing, into a reactor, a raw material compound that is represented by the formula (X) and in which Mw/Mn, representing the molecular weight distribution, is 1.30 or below, an inert gas, a fluorine gas, and a solvent; and fluorinating the raw material compound. Formula (X): R4-O-(R1-O)x-R5 (wherein R1 represents a divalent hydrocarbon group having 2 to 5 carbon atoms, R4 and R5 independently represent a hydroxyl-group-protecting group, and x represents the average degree of polymerization and is a real number from 2.7 to 15).
