ANALYSIS OF A PS PMMA BLEND BY IMAGE-PROCESSING TECHNIQUES

Concepts of image analysis by mathematical morphology were applied to the characterization of the morphology of an incompatible polymer blend (PS/PMMA) processed on an extruder. The morphologies originated from the breakup of particles according to a Rayleigh mechanism. We tried to estimate the initial length and radius of fibers using a specific particle labelling to check if the Tomotika's relation between the fiber radius and the characteristic length associated with breakup was, in our case, verified. The covariance function's method was also applied. More generally, the contribution of mathematical morphology to polymer morphology characterization was outlined.
