Phase separation in polymer blends has been monitored by u.v. absorption spectrophotometry. An 'absorption' peak forms in the early stages of phase separation and moves to longer wavelengths and broadens as the morphology ripens. This method may provide a useful alternative to scattering techniques to monitor phase separation
