Abstract
Disclosed is a fluorine-containing composition which contains a fluorine-containing polymer that has repeating units respectively derived from (A) a fluorine-containing monomer that is an alpha-chloroacrylate having a fluoroalkyl group, (B) a monomer that has a linear or branched hydrocarbon group but does not have a fluoroalkyl group, and (C) a monomer that has a cyclic hydrocarbon group but does not have a fluoroalkyl group. This fluorine-containing composition is capable of providing a base such as a fiber product with excellent water repellency, especially strong water repellency.
