Crystallization Temperature vs. Cooling Rate: the Link with "Real-Life" Polymer Processes

A relatively new technology for calorimetry has recently been discussed for practical use and since then marketed by PerkinElmer under the name HyperDSC®. The detailed characteristics and use of this new mode of measurement, which represents a major step forward in Fast Scanning Calorimetry (FSC) as compared to Standard DSC, have been published.1-4 Controlled and constant scan rates of hundreds of degrees per minute and combinations thereof, both in the cooling and heating mode, are possible thanks to the small furnace size compared with the bulky furnace of the conventional heat flux DSC (Figure 1). Thanks to the power compensation design which supports accurate heat flow rate measurement, heats of transition, heat capacities, temperature-dependent crystallinities etc. can be established at the extreme rates applied. The short measuring times also provide the high throughput needed in e.g. combinatorial chemistry. Differential Scanning Calorimetry a p p l i c a t i o n n o t e
