Current textbooks of polymer physics commonly introduce the thermodynamic theory of glass transition, which describes the glass transition as a second2order phase transition. However ,people have generally accepted the point of view that the nature of glass transition is a kinetic process. We discussed the origin of the thermodynamic theory of glass transition and tried to figure out the false assumptions employed in this theory. First ,we pointed out that the famous Kauzmann paradox may not be a real paradox. Second ,we told the reader that the so2called entropy catastrophe in the result of Floryps lattice statistics of semiflexible polymer solutions may rest on a misinterpretation of the configurational entropy ,and the latter actually means free energy. Therefore ,combining the above paradox with the above catastrophe into the basic assumptions of the thermodynamic theory of glass transition may lead to an illusive result.
