Fluoropolyether group-containing polymer and production method therefor

Abstract

The present invention is capable of producing a fluoropolyether group-containing polymer, which is represented by general formula (1) (in the formula, Rf is a monovalent or divalent fluoropolyether group-containing polymer residue, X is independently a divalent organic group, and α is 1 or 2), preferably has a number-average molecular weight of 1,000 to 50,000 in terms of polystyrene, and has both a terminal olefin moiety easily converting a functional group and a secondary hydroxyl group having high reactivity, by causing an organometallic reagent having β-hydrogen, specifically, an organometallic reagent having an aliphatic unsaturated double bond (olefin moiety) at a terminal thereof and having β-hydrogen, to act on a fluoropolyether group-containing polymer having a carbonyl group at a terminal thereof.
