Flow-induced crystallization in polyolefin blends: supporting data files and images

Polyolefins, including polyethylene and polypropylene, are some of the most common plastics in use today. Unfortunately, the recycling rates of these polymers is low due to separation difficulties. Because of this, understanding the properties of polyolefin blends is of particular interest. Using a combination of rheology, Raman spectroscopy, microscopy, and differential scanning calorimetry, we studied the rheological properties and crystallization kinetics of polyolefin blends under shear as a function of composition. This data is described in: Coughlin, M.L.; Huang, D.E.; Kotula, A.P.; Migler, K.B. (2024). Flow-induced crystallization in polyolefin blends, submitted for publication. Data include SEC traces, rheology data, Raman spectra, polarized optical microscopy images, DSC traces, and SEM images.
