A surface treatment agent, which can impart the excellent water- and oil-repellency, soil resistance and feeling to the substrate, is obtained from a fluorine-containing polymer which contains: (A) a monomer which comprises; (A1) a fluorine-containing monomer of the formula: CH&#x2550;C(&#x2014;X)&#x2014;C(&#x2550;O)&#x2014;Y&#x2014;Z&#x2014;Rf wherein X is a hydrogen atom, a monovalent organic group, or a halogen atom, Y is &#x2014;O&#x2014; or &#x2014;NH&#x2014;, Z is a direct bond or a divalent organic group, and Rf is a fluoroalkyl group having 1 to 20 carbon atoms, and (A2) a (meth)acrylate monomer having a cyclic hydrocarbon group, and (B) at least one functional organopolysiloxane selected from the group consisting of a mercapto-functional organopolysiloxane, a vinyl-functional organopolysiloxane, a (meth)acrylamide-functional organopolysiloxane and a (meth)acrylate-functional group.

Fluorosilicone polymers and surface treatment agent

There are provided novel crosslinked fluorine-containing elastomer fine particles, a process for preparing crosslinked fluorine-containing elastomer fine particles and a resin composition comprising the same. The crosslinked fluorine-containing elastomer fine particles are crosslinked fluorine-containing elastomer fine particles having a gel fraction of not less than 85% by mass or crosslinked fluorine-containing elastomer fine particles obtained by crosslinking fluorine-containing elastomer particles having at least three iodine atoms per one polymer molecule at an end thereof. The composition is one comprising those fine particles and a synthetic resin. The preparation process is a process for preparing crosslinked fluorine-containing elastomer fine particles, characterized by subjecting peroxide-crosslinkable fluorine-containing elastomer particles to peroxide-crosslinking by heating an aqueous dispersion comprising the fluorine-containing elastomer particles, a peroxide and a polyfunctional unsaturated compound.
