Abstract

A series of new functionalized poly(arylene-ether ketone) copolymers has been prepared by the nucleophilic aromatic displacement reaction from 4,4'-difluorobenzophenone and mixtures of bisphenol-A and 2,2'-bis(3-allyl,4-hydroxyphenyl)-hexat Luoropropane (6F-DABA) in the presence of potassium carbonate. The propenyl functional groups are statistically distributed along the polymer backbone and their concentration was tailored by adjusting the concentration of the starting monomers. These functionalized poly(aryleneether ketone)s (FPAEK) were used as thermoplastic modifiers for a bismaleimide (BMI) resin. The influence of the propenyl group concentration on the toughness of BMI,'FPAEK blend systems was studied.
