FLUOROPOLYMER PRODUCED BY AQUEOUS POLYMERIZATION USING DISPERSED PARTICULATE OF FLUORINATED IONOMER PRODUCED IN SITU
摘要
<p>A process for making an aqueous dispersion of fluoropolymer particles by polymerizing in a first polymerization step at least one fluorinated monomer having an ionic group in an aqueous polymerization medium in the presence of initiator, the polymerizing providing dispersed particulate of fluorinated ionomer, and polymerizing in a second polymerization step at least one fluorinated monomer in the aqueous polymerization medium in the presence of the dispersed particulate of fluorinated ionomer and initiator to form the aqueous dispersion of particles of fluoropolymer.</p>
