Abstract
A new porous polytetrafluoroethylene (PTFE) and a process for the production thereof is provided. Both the PTFE and the process excel by the fact that polytetrafluoroethylene is radiation-chemically degraded, the degraded polytetrafluoroethylene is mixed with a high-molecular emulsion polymerisate of polytetrafluoroethylene and the mixture is extruded, stretched and may additionally be sintered.
