Effects of Molecular Structure, molecular structure characteristics such as molecular weight. This chapter presents, for convenience of reference, some useful relationships in summary form. While there is some duplication of material given earlier, it is felt that the reader will find this useful. Numerical values of parameters a

Rheology of Thermotropic Liquid Crystal Polymers, a “mesomorphic” state or “mesophase,” and the molecular structural elements responsible for its formation are called “mesogens.” Liquid crystals do not have the three dimensional order of position of the molecules of solid crystals and are therefore capable of flowing like fluids. Unlike ordinary f

Role of Rheology in Film Blowing and Sheet Extrusion, an annular die. The extruded melt, in the form of a tube, flows upward under the influence of a vertical, “machine direction” force, applied by means of nip rolls some distance above the die. There is an overall stretching of the polymer in the machine direction, and the ratio of the linear speed o
