The authors describe the development of an apparatus for studying the light scattering during SSF of polymer blends and some preliminary results for a 50/50 blend of poly(ethylene vinyl acetate), EVA, and solution chlorinated polyethylene (SCPE). Light scattering experiments during shear flow of EVA/SCPE blends indicate that stress improves the miscibility of the two polymers. This is interpreted in terms of a stress-dependent phase diagram in which the phase boundary of a polymer mixture that exhibits a lower critical solution temperature is shifted upwards in temperature due to the application of stress. The phenomenon required a critical stress, but in the case of the EVA/SCPE, this is relatively low and improvements in miscibility were observed at temperatures of nearly 30°C above the cloud point.

We present some preliminary evidence on the variation of polymer density with film thickness. Our studies are still at an early stage but nevertheless our results point out strongly the necessity of considering interfacial effects when thin films are involved. We studied the influence of annealing on the structure of two-layers approximately 1000 angstrom thick of dPMMA, one of high and one of low molecular weight. From the results it seems that the molecular weights of the dPMMA do not influence greatly the scattering length densities of the polymer. However, the film thickness plays a major role in the resulting magnitude of the density.
