Abstract: 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: CH2?C(—X)—C(?O)—Y—Z—Rf wherein X is a hydrogen atom, a monovalent organic group, or a halogen atom, Y is —O— or —NH—, 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.

Abstract: 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.

Abstract: The present invention provides an electrical double layer capacity comprising a non-aqueous electrolytic solution comprising (A) a solvent comprising a specific fluorine-containing cyclic carbonate and (B) an electrolyte salt comprising a cyclic quaternary onium salt comprising cyclic quaternary onium cation and PF6?, (CF3SO2)2N? or (C2F5SO2)2N?, and (C) a polarizable electrode, and having high withstanding voltage and assuring excellent solubility in a wide range of solvents for dissolving an electrolyte salt.
