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

Assuming that the viscosimetric behaviour at low frequencies is mainly determined by the behaviour of the continuous phase, it becomes possible to explain the behaviour of PS/PMMA blends from a limited number of hypotheses. The main hypothesis is tha

A new torsion dilatometer is presented which allows simultaneous measurement of shear deformation, twisting moment, volume variation and axial deformation (or normal force). It is intended to be utilized principally for studies of volume changes duri

New photochromic polymers were prepared by deactivating living homo or block copolymers with various 2H-chromene-2-spiro-2′-indolines (3a–3d). Classical anionic polymerization was used throughout this work. By varying the chemical nature of the b
