Provided the structure is known, a method has been developed using the Rietveld technique on X-ray powder data collected on a commercial diffractometer to determine the amount of crystallinity in a polymer film such as poly(fl-hydroxybutyrate). This film was found to be 46% crystalline for a fresh sample and 60% when degraded
