| 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. |

| Keywords: | Molecular structure of rigid chain Dihedral angle Melting point Glass transition temperature |
