A spherulite of PEO is imaged during spin-coating using a combination of crossed polarizers and white-light stroboscopic microscopy. The interplay between the phase separation and crystallization in polymer blends during spin-coating is investigated by J. R. Howse and co-workers on page 7033, revealing the appearance of Bernard cells during the phase separation process and that, critically in blends of PS:PEO, phase separation occurs first, which is then followed by crystallization.
