The paper reviews the current available literature on the rheological behaviour of Ultra High Molecular Weight Polyethylene (UHMWPE)/ solvent systems. The rheological behaviour of UHMWPE /solvent systems was found to depend on the selection of solvent, shear rate, concentration of polymer, temperature and shear history. The influence of solubility on the rheological characteristics was discussed. The implication of the reports on gel spinning was also discussed.
