Abstract: The New aromatic polyarylether ketone is synthesized by new monomers, the general properties are studied by IR, DSC, WAXD.The results indicate that the new aromatic polyaryl ether ketones have the same crystal structure as PEEK.The glass transition point and the melting temperature get higher with the increasing of the ketone content of polyarylether ketone

Key words: Polyarylether ketone, Melting temperature, Melting heat, Entropy change
