Measuring crystallization by thermal analysis

The properties of semi-crystalline polymers are significantly influenced by the crystalline structure, which depends on the chemical structure, additives and process conditions. Webinar attendees will learn about the theory of crystallization and see crystallization examples investigated by differential scanning calorimetry (DSC) and Flash DSC. The presenter will demonstrate that the heating and cooling rates have a major influence on the reorganization and crystallization of polymers.

Understanding the crystallization behavior of polymers is important for characterization, compounding and processing of polymers. A standard technique for crystallization measurements is conventional differential scanning calorimetry (DSC) and the temperature modulated DSC.

Recently, fast scanning calorimetry has been used in cooling to analyze the crystallization behavior at processing conditions.

In this webinar we will present typical polymer examples measured by DSC and Flash DSC, with a special focus will be on crystallization and reorganization.

This webinar covers the following topics:

  • The classical theory of nucleation and crystallization
  • Isothermal and non-isothermal crystallization kinetics
  • Cold-crystallization and reorganization
  • Influence of nucleation agents, additives and filler on the crystallization behavior
  • Selection of sample and instrumental conditions for improved measurements

Key Takeaways

  • Understand the crystal structure of polymers
  • Discover how crystallinity influences mechanical properties
  • Learn which factors affect the crystalline structure of polymers


Dr. Teresa Dennenwaldt, Thermal Analysis Senior Applications Chemist, Mettler-Toledo, Analytical

Dr. Teresa Dennenwaldt obtained her Ph.D. in chemistry in 2013. During her dissertation at the Institute of Physical Chemistry, Ludwig Maximilian University (LMU) in Munich, Germany, she specialized in the investigation of novel oxide- and nitride-based nanostructured materials by transmission electron microscopy (TEM) and its analytical techniques.

After successfully completing her Ph.D., she joined the Max Planck Institute for Iron Research (MPIE) in Düsseldorf, Germany for one year and the Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland for three years as a postdoc in the field of electron microscopy and spectroscopy. In 2018, she joined Mettler-Toledo AG as an application specialist for thermal analysis. In her current position, she uses, teaches and supports DSC, TGA, TMA and DMA instruments at the Mettler Toledo AG head office in Switzerland.
