In the preceding paper of this series (N. Nakajima and E. R. Harrell, J. Colloid Interface Sci. 238, 116 (2001)), the pseudo-plastic behavior of PVC plastisol was analyzed to explain that the shear rate dependence of viscosity was a result of the formation of immobilized layer. The idea of the immob

Plastisols of poly(vinyl chloride), PVC, are suspensions of fine particles in plasticizer with about 50% resin volume fraction. Typically, the gross particle size ranges from 15 to 0.2 &mgrm and smaller, where the common practice of spray-drying these resins and subsequent grinding of larger particl

PVC plastisol exhibits pseudo-plastic flow in steady shear; that is, viscosity decreases with the increasing shear rate. At higher shear rates viscosity reaches a minimum and then increases, i.e., dilatant behavior. Previously, pseudo-plastic behavior was explained by a mechanism in which the suspen

A few percent of poly(butylene)-b-poly(tetramethylene glycol) was able to turn a liquid plasticizer into a gel, and thus imparted yield stresses to the fluid. When the plasticizer contained as little as 2.5 wt % of the block copolymer, sag free plastisols were obtained. A reduction in tensile streng
