We plan to study the effect of both oscillatory and steady state shear flow on the mesoscopic structure of polymer blends. A central feature of this proposal is the design and build of a rheometer for use with small angle neutron scattering. This will enable the simultaneous measurement, and hence correlation, of rheological properties and structure. It differs from existing facilities in that it is specifically aimed at viscoelastic materials with a high viscosity. We will study both polystyrene blended with is deuterated analogue, and blends of polystyrene/polyvinylmethylether and polyethyleneoxide/ polymethylmethacrylate. In each case both blend components will be highly entangled. We will meaure the anisotropy of the scattering pattern in the one phase region, and use this information to verify or otherwise recent theoretical predictions. We will also measure the structures that exist within the two-phase region, caused by shear induced phase separation.
