Popis: |
A series of new poly(phosphine oxide ether ketone)s has been prepared from bis[4-(4-fluorobenzoyl)phenyl]phenylphosphine oxide (1) and various bisphenols by the aromatic nucleophilic substitution reaction in DMAc. Monomer 1 was readily prepared by Friedel–Crafts acylation from bis(4-chloroformylphenyl)phenylphosphineoxide and fluorobenzene. Film-forming polymers were produced which have inherent viscosities ranging from 0.76 to 1.32 dl/g. These polymers are thermally stable to more than 500°C in air and exhibit glass transitions at about 200°C. Water contact angles of these polymers ranged from 79 to 84°. |
