Abstract

The method of SANS was applied to study critical fluctuations and precipitates in blends of large molecules. The critical behaviour has been investigated for an oligomer blend: n-hexane/n-perfluorohexane; furthermore, for a blend with high molecular weight, PVME/d-PS, the growth of precipitates was measured by means of a double crystal diffractometer with a resolution of 10-5 Å-1.
