ABSTRACT:
The invention is a process for the nonaqueous polymerization of tetrafluoroethylene with functional fluorinated comonomers. The process uses low TFE to comonomer ratios to form copolymers with high molecular weight and low melt flow. The copolymers are useful as membranes in electrolytic cells or fuel cells.
