Labile end groups in fluorinated thermoplastics, in particular carboxyl and acid fluoride groups, are converted into carboxamide groups when the polymer is treated with an aqueous, ammonia-containing solution. The after-treated products have a pale color, do not cause corrosion during processing and can easily be taken from the molds in transfer molding.
