“…Values in the case of PVC-S higher than those of PVC mean better dispersion capability of PVC-S. These results coincide with previous studies finding the superiority of functionalized binder polymers (6,10,11,16).…”

“…This can be attributed to the depletion flocculation. Indeed, Jeon et al ͑1997͒, have studied adsorption of the same polyvinyl chloride ͑PVC͒ binder on oxide surfaces. They have shown that at high c adsorption saturates, i.e., free resin is accumulated in the system which may lead to depletion flocculation of primary aggregates.…”

SynopsisThe structure development in dispersions of magnetic barium ferrite particles in cyclohexanone with polyvinylchloride wetting resin was tested by oscillatory rheological measurements and orthogonal superposition of steady and oscillatory shear. The optimum dispersion is achieved at the resin concentration c ϭ c 0 , which corresponds to a minimum in the viscoelastic modulii. At c Ͻ c 0 the system is highly elastic, brittle ͑G Ј drops sharply and G Љ goes through a strong maximum at high strain͒, thixotropic and its relaxation spectrum, H(), is dominated by long relaxation times, , which indicates the existence of a strong network. At c Ͼ c 0 the system becomes less elastic, more flexible, less thixotropic and H() is dominated by short , which indicates that the structure formation in this case is dominated by small aggregates rather than a network. By superimposing steady and oscillatory shear we show that the steady shear dramatically break the structure and shifts H() to very short .
