ABSTRACT:
The phosphonated fluorotelomers of this invention are, or can easily be made to be, hydrophilic. When blended with inert fibrous materials they can be used to make diaphragms for electrolytic cells, particularly for chlor-alkali cells used in the production of chlorine, hydrogen and sodium hydroxide from brine. Ion-exchange membranes can also be made from these fluorotelomers. The fluorotelomers can be made by using free radical phosphonyl esters to terminate the polymerization of the selected fluorocarbons.
