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.
                            本发明提供了一种在高
氟液体溶剂中制造胶乳的两步法,包括第一步将以下混合物聚合在一起:i)1-2 份(按重量计)一种或多种非
氟化自由基可聚合单体,和 ii)1-9 份(按重量计)一种或多种在一个或多个位点上以自由基可聚合基团终止的高
氟化大单体,以形成种子颗粒的分散体;以及第二步,将所述种子颗粒与另外一种或多种非
氟化自由基可聚合单体(按重量计,相对于种子颗粒总重量的 10-1000%)聚合在一起。本发明还提供了一种精细胶乳,它包含高
氟化液体溶剂和平均粒径为 250 nm 或更小,更优选为 200 nm 或更小的分散颗粒。本发明的胶乳可用于电泳显示。
