Resumen:
A modification of Lodge.s rubberlike-liquid theory postulated by M. H. Wagner has been used to model therheological behavior of commercial linear lowdensity polyethylene (LLDPE). Experimental results from steady and start-up shear deformation, and sinusoidal dynamic oscillations have been obtained at several temperatures from 150 to 220°C. It was found that Wagner.s equation gives an excellent fit to the LLDPE melt material properties on the whole range of times and deformations coveredby this work.
