Abstract
Studies of ethylene/1-octene copolymers prepared by a metallocene catalyst were carried out through dynamic-mechanical experiments (DMTA), differential scanning calorimetry (DSC), Raman spectroscopy and gel permeation chromatography (GPC). The influence of comonomer content on the ethylene/1-octene properties, specially those related to the dynamic- mechanical behaviour were studied. It was observed that the intensity of the ?-transition increases as the comonomer content increases and decreases crystallinity.
