SUMMARY
In this research, liquid natural rubber (LNR) was directly mixed with polyethylene (PE) and was compressed at 150oC. The PE was then separated and migrated to form a thin film on the rubber surface during the vulcanization process. The tensile properties of composite film were rising with increasing the PE contents from 15 to 150 phr as well as the ozone aging properties. The surface topography of the composite film was examined by using scanning electron microscopy (SEM) and was found that the PE form lamellar crystallites on the rubber interface after ozone treatment. The effect of PE on NR cross-linking was also investigated using S K-edge XANES Spectroscopy.
