Abstract.

A novel morphology for linear ABC-triblock copolymers is presented, where A forms spherical microdomains, covered by small B-spheres and C forming the matrix. This morphology is characterized by transmission electron microscopy and small angle X-ray scattering. The morphology forms both in solution cast and melt extruded samples. Qualitative arguments to understand the thermodynamic stability of this morphology are given.
