The Newtonian mixing rules for several binary systems have been experimentally investigated. Some systems show non-ideal mixing response and for some systems the non-ideal response is pressure-dependent, yielding an opportunity for manipulation of the pressure-viscosity behavior to advantage. The mixing of differing molecular weight “straight cuts” can produce very different pressure-viscosity response. This behavior underscores the difficulty in predicting the pressure-viscosity coefficient based upon chemical structure and ambient viscosity since the molecular weight distribution is also important, but it also provides another opportunity to control the high-pressure response by blending. The first experimental observation of double shear-thinning within a single flow curve is reported. Blending then provides the capability of adjusting not only the Newtonian viscosity but also the non-Newtonian shear-thinning response as well.

Viscosity Behavior

Abstract The concept of latex concentrate processibility and its relation to raw latex properties and proposed chemical stability tests is examined. The KOH number of latex is shown to have only a limited value as a criterion of latex properties. A new test is proposed based on the viscosity behavior on storage of a fully compounded latex. This test is experimentally compared to other proposed tests, raw latex properties, and the influence of various additives. Methods of controlling latex compound viscosity are suggested.
