We proposed three degrees n” of phenyl substition on the middle phenylene core of novel poly(arylene ether)s (PAEs). The PAEs were prepared via nucleophilic displacement of fluorine atoms on the terminal benzene ring with trifluoromethylactivated bisfluoro monomer. The thermal property of polymers showed ~273 0 C glass transition point and ~457 0 C decomposition temperature for 5% weight loss. ...

INTRODUCTION Concerns regarding UHMWPE wear particle induced osteolysis [1] have led to investigations of alternative bearing materials. Carbon-fibre reinforced poly-ether-ether-ketone (CFR-PEEK) has been shown in animal studies to have a similar biological activity to UHMWPE [2], whilst hip and knee configurations incorporating this polymer display reduced wear rates when compared with convent...
