Abstract

An aromatic bisphenol which contains bulky tertiary butyl group, 5-tert-butyl-1,3-bis(4-hydroxybenzoyl)benzene (2) was synthesized in high yield and purity by the reaction of 5-tert-butyl-1,3-bis(4-fluorobenzoyl)benzene with KOH solution in presence of DMSO. It was polymerized with activated bisarylhalides via aromatic nucleophilic substitution reaction to prepare a series of high molecular weight poly(arylene ether ketone)s (P1-P5), containing pendant tertiary butyl groups. The effect of molecular structure on the physical, thermal, mechanical and adhesion properties of the polymers were investigated.
