Patent ID: 7973091

Claim:
A process for producing flowable and liquid dispersible particles of a highly fluorinated ion exchange polymer, comprising: providing a dispersion of a highly fluorinated ion exchange polymer in a liquid comprised of from 10 to 60 wt % of an organic liquid, atomizing said dispersion to produce droplets of the dispersion, releasing the dispersion droplets into a heated inert gas, drying the dispersion droplets in the heated inert gas to produce polymer particles wherein the polymer particles agglomerate during drying, and the agglomerated particles have a mean diameter in the range of 1 to 100 microns and which agglomerated particles, upon drying, produce flowable particles of highly fluorinated ion exchange polymer wherein the flowable polymer particles have dry surfaces and an internal residual moisture content in the range of from 4 to 10 wt % of at least 4 wt %.
