Abstract

Solutions of copolymers of the tetrafluoroethylene/ethylene type Copolymer solutions comprising tetrafluoroethylene, ethylene and, as appropriate, further .alpha.-olefinic monomers in low-molecular-weight polymers of chlorotrifluoroethylene are described. They can be used for coatings, impregnations, cast films and for the production of fibers and filaments by gel spinning.
