Available in PDF, EPUB and Kindle. Book excerpt: A technique to study the kinetics of flow-induced crystallization of polymers in extensional flow has been developed which uses a 4-Roll Mill. The kinetics of a High Density Polyethylene were found to be well described by the Avrami treatment, indicated that the crystallization occurred by sporadic nucleation and one-dimensional growth and were a strong function of temperature and applied stress but were independent of strain history. The kinetics were found to be consistent with the Ziabicki theory for strain-induced crystallization but inconsistent with the theory of uttermost uniformity and an elevated melting point mechanism. The kinematics and stress fields of the 4-Roll Mill flow were measured independently by a tracer particle technique and an application of the Method of Isoclinics respectively allowing comparison to the predictions of several rheological equations of state. The deformation of a polymer droplet suspended in a carrier phase at low Reynolds number and high Weber number was documented. It is recommended that the 4-Roll Mill technique be used for study of other crystallizable polymer systems.

Available in PDF, EPUB and Kindle. Book excerpt: A flow visualisation cell was used together with image capture and image processing systems to observe the convergent flows of polymer melts in steady state single screw extrusion through a slit die. This technique provided useful information for assessment of any vortex and entry flow patterns for different flow conditions and various polymer types. Entry flow patterns are characterised in terms of natural entry profile, vortex boundary profile, location of vortex centre and detachment length. Stress birefringence provides principal stress difference measurements, which can be obtained from the digital image analysis of isochromatic fringes. The assessment of stress distribution in terms of centre line principal stress difference (PSD) or the extensional stress along the centre line of a slit, shear stress and first normal stress difference are obtained from the digitised isochromatic and isoclinic fringes together with stress optical coefficients via the stress optical law. Stress distributions can be combined with flow velocity measurements for the full entry flow. Average strain rate fields for the polymer melts flow at various flow conditions and different polymer types are therefore obtained. This technique also provides the assessment of apparent extensional viscosity from the ratio of extensional stress (...) and extensional strain rate (...). Two different approaches of the extensional viscosity assessments: particle tracking and digitised entry profile methods are established. Fully developed flow regions in terms of entrance and exit length for polymer melt flows of various flow conditions are determined using gradients of centre line extensional stress (or PSD) and the parallel patterns of isochromatic fringes in a downstrewn slit.
