Abstract
The invention relates to a process for the preparation of powder form polymer mixtures consisting of a tetrafluoroethylene polymer and an organic thermoplastic polymer, the tetrafluoroethylene polymer being present in the compositions in a particulate, highly disperse form; the powder form polymer mixtures thereby obtained have special and surprising properties when they are processed in a thermoplastic manner to give plastics articles and when they are added to conventional thermoplastics.
