Abstract

Critical behaviour of PSD-PVME polymer blends are presented. Spinodal and binodal transition temperatures have been determined by the use of a SANS-camera, and non-meanfield characteristics have been observed close to the critical point. A dynamic decomposition study has been performed by the use of a neutron double crystal diffraction.
