Abstract:
A process for producing flowable and liquid dispersable particles of a highly fluorinated ion exchange polymer is provided in which a dispersion of a highly fluorinated ion exchange polymer in a liquid comprised of at least 10 wt % of an organic liquid is provided, atomized to produce droplets, and released into a inert heated gas. The dispersion droplets dry to produce flowable particles of highly fluorinated ion exchange polymer having dry exterior surfaces and an internal residual moisture content of at least 4 wt %.
