Application of Rheology to Polymer Processing,rocessed since it is stable in the melt but only soluble with some difficulty. Polyacrylonitrile and its copolymers, in comparison, are soluble but infusible, so that they are always processed in solution.

The Basic Equations of Non-Newtonian Fluid Mechanics,n described mathematically with a degree of success. We can imagine solving a fluid flow problem, in theory, by considering every individual particle and interaction in a system and solving the equations that govern them. These types of equations are very difficult and such systems have only been so

Micro-Rheological Modelling,s, blends, block copolymers, or other complex materials, is due to the “structure” of the material at the scale of, say, 1 µm. Thus a valuable alternative to the classical approach to rheology, originally founded in continuum mechanics, is one which starts from a consideration of the micro-structure

Linear Viscoelasticity,the relaxation time spectrum which depends on the molecular details. To address an unsolved problem in rheology, the search for relations between molecular architecture and relaxation, we propose to start out with the most simple molecular architecture and later add molecular details. This proposal

Temperature Behaviour of the Viscoelastic Material Functions in Polymers,arts with solid pellets at a temperature about 0.6 to 0.8 times the glass transition temperature T.. The pellets usually feed a plasticating screw, where they are deformed and heated up to a melt (at a temperature T~ 1.3 T. to 1.5 T. for thermoplastics, higher for elastomers). Later the melt flows t

The Rheology of Multiphase Systems,l relations. The continuity principle requires that there be no discontinuity of material properties from one point to another, the homogeneity means no concentration gradient, and the isotropicity implies that the flow does not impose orientation on the flow elements. In the multiphase systems thes
