Method of producing fluoropolymer

Abstract

Provided is a fluoropolymer represented by the formula Af-CRP, where Af is a fluoropolymer segment containing more than 80 mol % of a polymerized unit based on tetrafluoroethylene; and CRP is any of the formulas (CRP1) to (CRP5); the formula (CRP1) being —SC(S)Zc11 (where Zc11 is an alkyl group or an aryl group), the formula (CRP2) being —SC(S)Zc12 (where Zc12 is an alkyl group or an aryl group), the formula (CRP3) being —SC(S)SRc11 (where Rc11 is a monovalent organic group), the formula (CRP4) being —SC(S)NZc132 (where Zc13s are (i) each independently an alkyl group, an aryl group, or a 4-pyridyl group or (ii) groups bonded to each other to form a heterocycle together with a N atom in the formula), and the formula (CRP5) being —SC(S)OZc14 (where Zc14 is an alkyl group or an aryl group).
