- Characteristics of Flow Curves for Blends of Immiscible Polymers with Intersecting Flow Curves
抄録
Characteristics of flow curves for the blends of immiscible polymers, whose flow curves intersect each other, were investigated by computer simulation based on the concentric multi-layer model proposed previously. Flow curves of component polymers were approximated by the power-law. Calculations were performed for a few combinations of power-law indexes and for various blending ratios. Following results were obtained. (1) Flow curves for the blends with various ratios intersect at the same point as those of parent polymers do. (2) Flow curves lie in the order of blending ratio. (3) Flow curves are similar to that of a lower viscosity component at either side of the cross point on flow curves of parent polymers. (4) The region on flow curves, where the conventional blending rules on viscosity are applicable, depends on the ratio of power-law indexes of parent polymers and the value of shear rate and viscosity at the cross point. A good agreement between predicted and experimental results were attained for the blends of polystyrene and high density polyethylene.
