TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The hydrolysis and/or polycondensation of (I) is carried at room temperature or upon heating at temperatures lower than 100 degrees C. In step (b): (F1) and the aqueous medium comprising the pre-gelled metal compound are reacted in the molten state at 100-300 degrees C, preferably 150-250 degrees C, as a function of the melting point of (F1); and (F1) is blended with a non-functional fluoropolymer prior to reaction with the pre-gelled metal compound. an inorganic filler is further used in step (a) and/or step (b). Preferred Components: (F1) comprises: recurring units derived from at least one fluorinated monomer or at least one comonomer comprising at least one hydroxy group (comonomer (MA)); and at least 0.01 mole%, preferably at least 0.1 mole% recurring units derived from (MA); and atmost 20 mole%, or at most 3 mole recurring units derived from (MA). (F1) comprises: recurring units derived from at least one fluorinated monomer and at least one comonomer; at least 0.01 mole%, preferably at least 0.1 mole% recurring units derived from (MA); and atmost 20 mole%, or at most 3 mole% recurring units derived from (MA). The comonomer (MA) is (meth)acrylic monomers of formula (C(R1)(R2)=C(R3)(C=O-O-R1a)) (II) or vinylether monomers of formula (C(R1)(R2)=C(R3)(-O-R1a)) (III). (I) is of formula (R14-m1E(OR2)m1) (Ia).R1-R3 = H or 1-3C hydrocarbyl;R1a = H or 1-5C hydrocarbyl comprising at least one OH;m1 = 1-4 or 1-3;E = Si, Ti or Zr; andR1, R2 = 1-18C hydrocarbyl (optionally comprising at least one functional group).(F1) comprises (a1) polymers comprising recurring units derived from (MA), at least one per(halo)fluoromonomer that is tetrafluoroethylene (TFE) or chlorotrifluoroethylene (OTFE), and at least one hydrogenated monomer comprising ethylene, propylene or isobutylene, optionally containing 0.01-30 mole% at least one additional comonomer or (a2) polymers comprising recurring units derived from at least one comonomer (MA), vinylidene fluoride (VDF) and optionally at least one fluorinated monomers different from VDF. The (a2) polymers comprise: at least 60 mole%, preferably at least 85 mole% (VDF); optionally 0.1-15 mole%, preferably 0.1-10 mole% fluorinated monomer comprising vinylfluoride, chlorotrifluoroethylene, hexafluoropropene, TFE, trifluoroethylene and/or perfluoromethylvinylether; and 0.01-20 mole%, preferably 0.1-10 mole% (II). The aqueous medium further comprises at least one organic solvent. The aqueous medium comprises at least one acid catalyst, water, and at least one alcohol. EXAMPLE - 200 g Tetraethoxysilane, 69.45 g water, 50 g ethanol and 2.69 g citric acid were introduced to 500 ml beaker equipped with magnetic stirrer running at a moderated speed and left under stirring for three hours at room temperature to obtain pre-gelled metal compound. The pre-gelled metal compound aqueous solution was fed using a peristaltic pump in the main feeder of the twin-screw extruder. 0.2 mol.% Vinylidene fluoride-hydroxyethylacrylate copolymer was added at 528 g/hour while the pre-gelled metal compound aqueous solution was fed at 472 g/hour. The pre-gelled metal compound aqueous solution was maintained under vigorous stirring to obtain fluoropolymer hybrid organic/inorganic composite pellets.
