Abstract:

Only a few reported studies have involved the uniaxial orientation of LPDE and even less on LLDPE. It is our purpose to report on characteristics of uniaxially oriented films of LLDPE that contribute to property development. The LLDPE has been coextruded at 25 and at 80 C layered as ribbons within longitudinally split billets of HDPE. The LLPDE so drawn were characterized by thermal analysis, birefringence, elastic recovery and wide-angle x-ray measurements. As a result we can conclude that the drawing of LLDPE at the low temperature produces a relatively high content of monoclinic crystals. Originator supplied keywords include Orientation birefringence elastic recovery wide-angle x-ray monoclinic low-density polyethylene.
