For many years, the thermodynamic description of macromolecules lagged behind other materials because of the unique tendency of pol5nneric systems to assume nonequilibrium states. Most standard sources of thermodynamic data are, thus, almost devoid of polymer information (1-7). Much of the aversion to include polymer data in standard reference sources can be traced to their nonequilibrium nature. In the meantime, polymer scientists have learned to recognize equilibrium states and utilize nonequilibrium states to explore the history of samples. For a nonequilibrium sample it is possible, for example, to thermally establish how it was transferred into the solid state (determination of the thermal and mechanical history). More recently, it was discovered with the use of temperature-modulated differential scanning calorimetry (TMDSC) that within the global, nonequilibrium structure of semicrystalline polymers, locally reversible melting and crystallization processes are possible on a nanophase level (8).

Temperature-modulated differential scanning calorimetry (T-MDSC) applies a thermal modulation in temperature to a conventional DSC mn and determines a dynamic heat capacity from the relationship between the modulation components of temperature and of heat flow. Primary application of this technique has been the measurement of specific heat capacity and the examination of the anomaly in a relaxation process such as alpha process related to the glass transition. An application to the first-order phase transitions of crystallisation and melting of polymer crystals has recently been suggested. The method and typical results are described. 13 refs. [Pg.81]

Modulated temperature differential scanning calorimetry (MTDSC, also called temperature modulated DSC or TMDSC) is an extension of conventional DSC in which a modulated temperature input signal is used This modern technique has proven to be very beneficial for the thermal characterisation of many materials, especially polymers [1-5].

Crystallisation behaviour of polyethylene (PE) has been intensively studied from both fundamental and application reasons [1-3]. One of the most commonly used techniques is differential scanning calorimetry (DSC). New information on PE crystallisation can be gained if modulated temperature DSC (MT-DSC), which uses a periodical temperature modulation over a traditional linear heating or cooling ramp, is applied. It makes it possible to separate reversing and non-reversing components of the total heat flow because of this characteristics of the MT-DSC technique, it can be regarded as a useful tool to study polymer crystallisation behaviour.
