Abstract
A novel morphology for linear ABC-triblock copolymers is presented, wh ere A forms spherical microdomains, covered by small B-spheres and C f orming the matrix. This morphology is characterized by transmission el ectron microscopy and small angle X-ray scattering. The morphology for ms both in solution cast and melt extruded samples. Qualitative argume nts to understand the thermodynamic stability of this morphology are g iven.
