in this research, high oxygen-barrier films were organized based on low-density polyethylene (ldpe)/ ethylene vinyl alcohol (evoh)/ polyethylene-grafted maleic anhydride (ldpe-g-ma) compatibilizer. the effects of 10–30 wt. % evoh and 0–10 wt. % ldpe-g-ma loadings on the properties of final films were evaluated. the morphology of specimens was observed by using scanning electron microscopy (sem)...

The space charge distribution in low-density polyethylene (LDPE) was measured with the pulsed electroacoustic (PEA) method. We used three types of LDPE: LDPE-L and LDPE-H were prepared by the high pressure process, and m-LDPE was polymerized with a metallocene catalyst. Space charge in LDPE strongly depended upon the electrode material. Semiconductive electrodes enhanced carrier injection into ...

The influences of short chain branching (SCB) and molecular weight (Mw) of low density polyethylene (LDPE) on its melt miscibility with polypropylene (PP) were investigated by rheological techniques. Rheological measurement and different data-treatment techniques as well as rheological models suggest that blends of PP with LDPE of high SCB (22 CH3/1000 C) are miscible at all compositions. Howev...
