A controlled fluorination method using elemental fluorine has been used to synthesize a large variety of new compounds from hydrogen-containing precursors including perfluoroethers, perfluoropolyethers, perfluoro crown ethers, and perfluorocryptands. Polyesters were converted to polyethers using a combination of direct fluorination of the carbon hydrogen bonds and fluorination by SF4 of the carbonyl groups. A process was developed for partial fluorination of gas separation membranes. The selectivity of the membranes for size separation was increased significantly.
