Nucleation and crystallization in polycaprolactone (PCL) — •Andreas Wurm1, Doris Pospiech2, and Christoph Schick11University of Rostock, Institute of Physics — 2Leibniz IPF Dresden e.V.

Crystallization is commonly considered as nucleation followed by a growth process. Nevertheless, a complete description of polymer crystallization is far from being achieved. Here we apply the recently developed technique, differential fast scanning calorimetry (DFSC), for the investigation of polycaprolactone (PCL) of different molecular weights. DFSC allows temperature control of the sample and determination of its heat capacity during temperature treatments at high cooling and heating rates (up to 500,000 K/s). We can derive information about kinetics of crystal nucleation and overall crystallization in the whole temperature region between glass transition and melting temperature.
