摘要： The present invention provides a non-film-forming latex of dispersed particles which may be used in an electrophoretic display, comprising: a) a highly fluorinated liquid solvent, and b) dispersed particles comprising a polymer comprising units according to formula I: wherein each (fcp) is independently selected from highly fluorinated polymer chains and each Q is independently selected from —H and straight or branched non-fluorinated polymer chains (hcp). Latexes of dispersed particles having a very small particle size are especially provided.

摘要： The present invention provides a two-step method of making a latex in a highly fluorinated liquid solvent, including a first step of polymerizing together a mixture of: i) 1-2 parts by weight of one or more non-fluorinated free-radically-polymerizable monomers, and ii) 1-9 parts by weight of one or more highly fluorinated macromers terminated at one or more sites with free-radically-polymerizable groups to form a dispersion of seed particles; and a second step of polymerizing together said seed particles with an additional 10-1,000 percent by weight, relative to the total weight of the seed particles, of one or more non-fluorinated free-radically-polymerizable monomers. The present invention additionally provides a fine latex comprising a highly fluorinated liquid solvent and dispersed particles having an average particle size of 250 nm or less and more preferably 200 nm or less. The latexes of the present invention may be useful in an electrophoretic display.
