Title:
FLUOROPOLYMER AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/107889
Kind Code:
A1
Abstract:
Provided is a fluoropolymer comprising a monomer (I) represented by general formula (I), wherein the content of a polymerization unit (I) based on the monomer (I) is 40 mol% with respect to the total polymerization units constituting the fluorpolymer, and the weight average molecular weight (Mw) is at least 1.4 × 104. General formula (I): CX2=CX–O–Rf–A (In the formula, X is independently F or CF3, Rf is a C1-40 fluorine-containing alkylene group, or a C2-100 fluorine-containing alkylene group having an ether bond or a keto group. A represents –COOM, –SO3M, –OSO3M or –C(CF3)2OM (wherein M represents –H, a metal atom, –NR7
4, an optionally substituted imidazolium, an optionally substituted pyridinium or an optionally substituted phosphonium, where R7 represents H or an organic group)).
