Abstract:
A method of making a latex comprising dispersed particles comprising the steps of:a) in a highly fluorinated liquid solvent, 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 b) in a highly fluorinated liquid solvent, 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.
