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) R—C(═O)—NH—R—O—R, (A2-2) CH═C(—R)—C(═O)—Y—Z(—Y—R), and (A2-3) XN(H)—R. 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.

Fluorine-containing polymer and surface treatment agent

A water repellent composition containing: (A) water repellent particles in which the number of surface alkyl groups on the water repellent particles is 600×10-50,000×10per 1 g of water repellent particles; (B) a water-repellent resin which is a polymer having a long-chain Chydrocarbon group; and (C) a liquid medium. The water-repellent particles preferably have an average primary particle size of 1-100 nm. Also disclosed is a method for treating a fiber using the water repellent composition, a method for producing a treated textile product, a film formed from the water repellent composition, and a textile product treated with a treatment liquid containing the water-repellent composition.

Water-repellent composition

Provided is a water repellent composition which does not use a fluorine-containing monomer, especially a fluoroalkyl group-containing monomer. A water repellent composition which contains (1) (a) a polymer which has a repeating unit derived from an amide group-containing monomer that is represented by formula: (wherein R1 represents an organic residue having an ethylenically unsaturated polymerizable group; R2 represents a hydrocarbon group having 7-30 carbon atoms; and R3 represents a hydrocarbon group having 1-5 carbon atoms) in an amount of 2-100% by weight relative to the polymer, and (2) a liquid medium.

Water repellent composition

Disclosed is a fluorine-containing polymer prepared by polymerizing (I) a polyfluoroalkyl group-containing (meth)acrylate which is substituted at alpha-position, in the presence of (II) a blocked isocyanate compound. A water- and oil-repellent composition containing the fluorine-containing polymer can impart the excellent water- and oil-repellency, and excellent durability thereof to substrates.

Fluoropolymers and treatment agent

Disclosed is a treatment agent for paper comprising a fluorine-containing copolymer having a repeat unit (a) derived from a fluorine-containing monomer represented by general formula (I): CH&#x2550;C(&#x2014;X)&#x2014;C(&#x2550;O)&#x2014;Y&#x2014;[&#x2014;CH)&#x2014;Z&#x2014;]&#x2014;(CH)&#x2014;Rf; a repeat unit (b) derived from at least one amino monomer represented by general formula (II-1): or a derivative thereof; and a repeat unit (c) derived from a pyrrolidone monomer represented by general formula (III): The treatment agent for paper provides paper having high oil resistance and high water resistance.
