Abstract
AbstractTwo novel poly (aryl ether ketone)s with anthracene moieties in the backbone were synthesized through the conventional nucleophilic aromatic substitution polycondensation for the first time, by using a new bisfluoro monomer, 9,10-bis(4-fluorobenzoyl) anthracene (AnBF). The structures of obtained polymers were confirmed by NMR, IR and UV characterizations. The polymers have high molecular weight and show good solubility in common organic solvents. Differential Scanning Calorimetry (DSC) indicates that they are vitrified polymers with high glass transition temperatures above 188° Thermogravimetric analysis (TGA) shows that these polymers have good thermal stability in nitrogen atmosphere with a 5% weight loss (TGA-5%) above 465°.
