PCT No. PCT/US89/02203 Sec. 371 Date Jun. 7, 1990 Sec. 102(e) Date Jun. 7, 1990 PCT Filed May 25, 1989 PCT Pub. No. WO89/11495 PCT Pub. Date Nov. 30, 1989.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 DEG -400 DEG C. for a time sufficient to convert -COOH and/or -COF groups to stable -CF2H groups, the resultant stabilized copolymers being useful, for example, in electrically conductive compositions having a good combination of melt flow and electrical conductivity. |
