ii series of new poly(phosphine oxide ether ketone)s has been prepared from
bis[4-(4-fIuorobenzoyl)phenyl]phenylphosphine oxide (1) and various bisphe
nols by the aromatic nucleophilic substitution reaction in DMAc. Monomer 1
was readily prepared by Friedel-Crafts acylation from bis(4-chloroformylphe
nyl)phenylphosphineoxide and fluorobenzene. Film-forming polymers were prod
uced which have inherent viscosities ranging from 0.76 to 1.32 dl/g. These
polymers are thermally stable to more than 500 degrees C in air and exhibit
glass transitions at about 200 degrees C. Water contact angles of these po
lymers ranged from 79 to 84 degrees. (C) 1999 Elsevier Science Ltd. AU righ
