Abstract: The full optimization structure of model compound ArOArCOArArCOArOAr is presented with average dihedral angle of 37.5°,Based on this ,the molecular structure is related to the melting point and glass transition for poly (aryl ether ketone) s and poly(arylether sulphone) s family with rigid molecular chain, The obtained relationship between them is well extended to predict the heat properties of the new family of aromatic homopolymers.

Key words: Molecular structure of rigid chain, Dihedral angle, Melting point, Glass transition temperature
