Title:
FLUOROPOLYETHER-GROUP-CONTAINING POLYMER, SURFACE TREATMENT AGENT, AND ARTICLE
Document Type and Number:
WIPO Patent Application WO/2017/212850
Kind Code:
A1
Abstract:
A surface treatment agent which comprises a fluoropolyether-group-containing polymer represented by the following formula (1) or (2)
Rf1-[N(V)β(E)γ]α (1)
Rf1-[Q-(G)δ-(E')ε-B]α (2)
and/or a product of partial (hydrolytic) condensation of the polymer. The surface treatment agent forms a cured coating film excellent in terms of water and oil repellency and resistance to abrasion with erasers.
(In formulae (1) and (2), Rf1 is a mono- or divalent polymer residue containing a fluorooxyalkylene group; N is C, Si, N, or a tri- to octavalent group optionally substituted by F; V is a monovalent group containing a hydroxy group or hydrolyzable group at the terminal; E is a monovalent group containing an oxyalkylene group; α is 1 or 2; β and γ are each 1-6, and β+γ is 2-7; Q is a single bond or a divalent group; G is a divalent group containing a hydroxy group or hydrolyzable group; E' is a divalent group containing an oxyalkylene group; B is H, an alkyl group, or a halogeno; δ is 0-10; and ε is 1-10.)
