Five polystyrene-poly(dimethylsiloxane) (PS/PDMS) diblocks were synthesized by sequential anionic polymerization, and their morphologies characterized by small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM). All materials are microphase-separated in toluene-cast films, and estimates of the interaction parameter χ indicate that these materials are all strongly segregated...
The coexistence curves of blends of polystyrene (PS, M w = 600 and 2.2 10 3 g mol -1 ) and poly(dimethylsiloxane) (PDMS, M w = 460, 1400, 3700 and 2.3 10 5 g mol -1 ) were determined using a specially designed refractometer. The coexistence curve of the oligomer blend PS (M w = 600)M w = 460) was of the upper critical...
