Abstract
A polymer composition of cross-linked fluoropolymers is provided, that is generated using a fluoropolymer compatibilizer. The cross-linked fluoropolymers have excellent mechanical and dielectric characteristics at high temperatures, making them useful for such applications as insulation for automotive communications cables and PCB laminates.
