ABSTRACT:
Thermally and hydrolytically stable fluorocopolymers, especially melt-processible fluorocopolymers, for example, tetrafluoroethylene/hexafluoropropylene copolymers, having --COOH and/or --COF groups on the polymer chains are contacted and reacted with a secondary or tertiary amine and heated at 160.degree. -400.degree. C. for a time sufficient to convert --COOH and/or --COF groups to stable --CF.sub.2 H groups, the resultant stabilized copolymers being useful, for example, in electrically conductive compositions having a good combination of melt flow and electrical conductivity.
