    摘要: Provided is a fluorinated polymer that can impart excellent washing durability and water- and oil-repellency to fibers, said fluorinated polymer having a repeating unit derived from a fluorinated monomer (a) that comprises a first fluorinated monomer (a1) represented by the formula: CH2═C(—X1)—C(═O)—Y1—Z1—Rf1 [wherein X1 represents a halogen atom; Y1 represents —O— or —NH—; Z1 represents a direct bond or a bivalent organic group; and Rf1 represents a fluoroalkyl group having 1 to 20 carbon atoms] and a second fluorinated monomer (a2) represented by the formula: CH2═C(—X2)—C(═O)—Y2—Z2—Rf2 [wherein X2 represents a monovalent organic group or a hydrogen atom; Y2 represents —O— or —NH—; Z2 represents a direct bond or a bivalent organic group; and Rf2 represents a fluoroalkyl group having 1 to 20 carbon atoms].

    摘要: A surface treatment agent which is an aqueous emulsion containing: (a) a fluorine-free polymer including: (i) repeating units derived from a long-chain (meth)acrylate ester monomer represented by the formula: CH2═CA11-C(═O)—O-A12, wherein A11 is a hydrogen atom or a methyl group, and A12 is a linear or branched aliphatic hydrocarbon group having 10-30 carbon atoms; (b) a surface active agent including both of a nonionic surface active agent and an anionic surface active agent, wherein the amount of the anionic surface active agent is at least 22% by weight, based on the total of the nonionic surface active agent and the anionic surface active agent; and (c) a liquid medium comprising water.
