Abstract

See full text

A fluorine-containing polymer including a repeat unit derived from a fluorine-containing monomer (A1) and a repeat unit derived from a hydrocarbon group-bearing fluorine-free monomer (A2). The fluorine-free monomer (A2) is preferably at least one monomer selected from (A2-1) R22—C(═O)—NH—R23—O—R21, (A2-2) CH2═C(—R32)—C(═O)—Y31—Z31(—Y32—R31)n, and (A2-3) X41N(H)r—R41. Also disclosed is a surface treatment agent containing (A) the fluorine-containing polymer and (B) a liquid medium, as well as a method for producing the surface treatment agent and a method for producing a treated substrate.
