Abstract: 1353535 Fluorocarbon polymers FARBWERKE HOECHST AG 22 July 1971 [25 July 1970] 34371/71 Heading C3P Ethylene is copolymerized with a fluoroolefin in an aqueous acidic medium at 0-25 atmospheres gauge pressure using as catalyst a manganese acid or manganese acid salt or a precursor therefor. In examples ethylene was copolymerized with tetrafluoroethylene, trifluorochloroethylene, trifluorochloroethylene and tetrafluoroethylene, vinyl fluoride and tetrafluoroethylene, or trifluorochloroethylene, or vinylidene fluoride and tetrafluoroethylene or trifluorochloroethylene using as catalyst potassium permanganate or manganate, or permanganic acid dihydrate. The polymerization medium was kept alkaline either by using a buffer such as ammonium chloride, nitrate or perfluorooctanoate or using acidic emulsifiers such as C 6 -C 10 perfluoroalkyl phosphonic acids or perfluorooctanoic acid. Diethylene glycol may be added as a regulator.

Abstract: : Mixtures of a) copolymers of ethylene and tetrafluoroethylene, which in addition optionally contain up to 10 mole % of units of at least one ethylenically monounsaturated monomer copolymerizable with tetrafluoroethylene, with b) phosphorus acids which in one of their tautomeric forms contain 2 or 3 oxygen atoms and 1 or 2 hydrogen atoms directly bonded to each phosphorus atom, or with salts of such acids, are described. These mixtures possess improved heat stability and can, where appropriate with interpolation of a melt granulation process, be used, in particular, for the coating of metals. Component b) is added to the copolymer a) in the dry form or preferably in the form of a solution during working up, and in particular is added either to the pulverulent copolymer or, more especially, to a moist product, isolated from dispersions, after the last washing process.
