Abstract:
A method for curing a fluorine-containing polymer having a structure of the formula: wherein R represents a straight or branched fluorinated alkylene group having 1 to 20 carbon atoms which optionally contains an oxygen atom; x and y represent mole percentages and x is from 1 to 100% by mole; A is â€”CN, â€”NCO, â€”COORâ€² in which Râ€² is a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, or A is an acid anhydride group or A is an unsaturated hydrocarbon group; and M is a repeating unit derived from a copolymerizable monomer; wherein the method comprises treating said polymer with ammonia and crosslinking said polymer through the side functional groups of said polymer.
