TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The fluorinated ionomer of the particulate comprises ionic groups having a negative logarithm of the acid dissociation constant (pKa) of less than 10. The fluorinated ionomer of the particulate comprises ionic groups comprising sulfonate (preferred), carboxylate, phosphonate, and/or phosphate. The fluorinated ionomer of the particulate in thermoplastic form has a melt flow at 270 degrees C using a 5 kg weight of 1-500. The aqueous medium contains less than 300 ppm of perfluoroalkane carboxylic acid or salt fluorosurfactant having 8 or more carbon atoms based on the weight of water in the aqueous polymerization medium. The recurring side chains have the structure of formula (-(O-CF2CFRf)a-(O-CF2)b-(CFR1f)cSO3X). The fluorosurfactant is of formula ((R1-On-L-A-)Y1+).Rf, R1f = F, Cl or 1-10C perfluorinated alkyl;a = 0-2;b = 0-1;c = 0-6;X = H, Li, Na, K or NH4;R1 = partially or fully fluorinated aliphatic group which may contain ether linkages, preferably CF3CF2CF2-;n = 0 or 1 (preferred);L = alkylene group which may be nonfluorinated, partially fluorinated or fully fluorinated and which may contain ether linkages, preferably -CF(CF3)-;A- = an anionic group comprising carboxylate (preferred), sulfonate, sulfonamide anion, or phosphonate; andY1+ = H, ammonium (both preferred) or alkali metal cation.Provided that the chain length of R1-On-L- is not greater than 6 atoms.    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The process further comprises: providing surfactant in the polymerization medium; providing fluorosurfactant in the polymerization medium; or providing fluoroether surfactant in the polymerization medium. The polymerizing produces less than 13 wt.% of undispersed fluorinated ionomer. In the process, during suspending the dispersed particulate of fluorinated ionomer is stored in separate vessel. The first polymerization step produces sufficient dispersed fluorinated ionomer particulate for carrying out the second polymerization step multiple times. Preferred Components: The dispersed particulate of fluorinated ionomer present in the aqueous polymerization medium in the second step comprises less than 15 wt.% of the fluorinated ionomer solids produced in the aqueous dispersion. The particulate of fluorinated ionomer has a weight average particle size of 2-100 nm. The fluorinated ionomer of the particulate has an ion exchange ratio of 3-53. The fluorinated ionomer of the particulate is highly fluorinated or perfluorinated. The fluorinated ionomer of the particulate comprises a polymer backbone with recurring side chains attached to the polymer backbone with the side chains carrying ionic groups. EXAMPLE - Demineralized water (1750 g), 30 wt.% of aqueous solution of ammonium perfluoro(3,6-dioxa-4-methyl-7-octene) sulfonate (0.6 g), and a 20 wt.% of aqueous solution of dimer acid salt (20 g) were charged in a reactor. The reactor was heated to 25 degrees C, and then evacuated and purged three times with tetrafluoroethylene (TFE). The reactor temperature was increased to 65 degrees C, and was pressured to 30 psig with TFE. Then, freshly prepared aqueous initiator solution (40 ml) containing 0.2% ammonium persulfate was injected. Then, this same initiator solution was pumped into the reactor at 0.1 ml/minute. After polymerization has started, additional TFE is fed into the reactor at a rate of 0.1 g/minute. Then, the process was suspended by stopping the TFE and initiator feeds slowly venting the reactor. After stopping agitation, the reactor vapor space was evacuated and worked up to give the clear dispersion of fluorinated ionomer particulate.
