Thermal behaviour of poly(2,6-dimethoxy-1,4-phenylene ether)

Thermodynamic properties of semicrystalline and completely amorphous samples of poly(2,6-dimethoxy-1,4-phenylene ether) have been studied by DSC-calorimetry. A very low entropy of fusion indicates that only minor conformational changes take place during the melting. The low value of the configurational entropy of the glass transition is due to the faci that the theoretical second order transition is closely related to the glass transition point.
