摘要
This latex (meth) acrylic fluorinated consists of a dispersion of particles or a mixture of dispersions of particles, these dispersions are obtained by emulsion polymerization in aqueous medium, at least one stage, at least one monomer perfluorinated of formula (i) have been used as a comonomer in the formation of the particles, and being distributed statistically in the particles formed by a stage or distributed statistically in the bark of structured particles of the type of core - shell, or core - layer (s), the intermediate (s) - bark resulting from a polymerization respectively to two stages and to more than two stages, the said latex is constituted by a dispersion of the structured particles or by a mixture of at least one dispersion of said particles structured, fluoro and / or at least one fluorinated statistical dispersion of said particles and of at least one dispersion of particles are non fluorinated. & br / (see appended drawing in bopi) & br / * * r 1 = ch3 or h; r * * 2 = alkyl perhalogenated, c1 - c10; and 0 ≦ n = 4.
