Live Q&Q with our experts

Crystallization of polymers occurs between the glass transition (Tg) and the melting temperature (Tm). Within this temperature range, molecular movement allows crystalline domains to form, which can occur during heating (cold crystallization) or during cooling from the melt. The crystal properties depend on the heating and cooling rates applied.

Understanding polymer crystallization behavior is essential for improving production processes, optimizing material properties, developing new materials, and conducting failure analysis. Thermal analysis techniques are ideal for studying crystallization behavior, which is critical for optimizing material properties and processing conditions.

Thermal Analysis Techniques for Investigating Polymer Crystallization

In the webinar, we show how differential scanning calorimetry (DSC) and Flash DSC in particular provide important insight into reorganization processes, which require an extremely wide range of heating and cooling rates. We also present analytical examples using thermomechanical analysis (TMA), dynamic mechanical analysis (DMA), and hot-stage microscopy (TOA).

The Polymer Crystallization Process

The crystallization process is initiated by a certain degree of cooling and begins with nucleation followed by growth. Heterogeneous nucleation is more common in polymers and can be accelerated by adding nucleation agents. Crystallization processes can be measured via non-isothermal crystallization, cold crystallization, and isothermal crystallization.
