Abstract
Modified tetrafluoroethylene dispersion polymers are prepared by polymerizing tetrafluoroethylene in the presence of perfluorinated vinyl ethers of the formula I ##STR1## as modification agent. The articles made from the polymers by paste-extrusion have improved mechanical and electrical properties even if the extrusion is carried out at a high reduction ratio and draw-off rate.
