Abstract: The present invention provides modified polyaryl ether ketones (PAEK)s having fluorinated moieties incorporated therein. The present invention also relates to a method for covalently attaching fluorinated moieties onto the surface of PAEK, said method comprising reducing the ketone groups of the PAEK to hydroxyl groups to obtain a modified PAEK and then reacting the hydroxyl groups with a compound bearing a fluorinated moiety.

Abstract: The present invention relates to modified fluorinated poly(arylene ether ketone)s that can be crosslinked to produce high performance thermoset useful for semiconductor application with low dielectric constant. The present invention also relates to a method for manufacturing said modified fluorinated poly(arylene ether ketone)s prepared via chemical transformation of carbonyl groups to hydroxyl pendant groups and following thermal curing.
