Abstract

The invention relates to a fluorinated ethylene propylene copolymer which is processed from the melt by fusion granulation and which consists essentially of monomer units of 78 to 95 wt. % tetrafluoroethylene, 5 to 22 wt. % hexafluoropropene and not more than 3 mol % fluorinated monomers that can be copolymerised with a mixture of tetrafluoroethylene and hexafluoropropene. Said copolymer has a molar ratio of weight average to number average of less than 2, has less than 80 unstable terminal groups per 1x10<6> carbon atoms and is produced by aqueous emulsion polymerisation. The copolymer is coagulated after polymerisation and then agglomerated. The agglomerate is isolated and dried to form a free flowing product, partial sintering being prevented. Said product is brought into contact with an effective amount of fluorine at a temperature between 60 DEG C and the preliminary sintering temperature, whereby unstable terminal groups are converted into stable terminal groups. The fusion granulate is advantageously treated with ammonia or a compound which liberates ammonia, in water. The product can be used for coating wires and cables.
