Grafting of Acrylamide to Low Density Polyethylene During Melt Processing
Acrylamide was grafted in low density polyethylene during melt processing in the presence of a free radical initiator using a torque rheometer in a closed system. Effects of processing time, acrylamide and benzoyl peroxide concentrations were studied. FTIR studies revealed that the degree of grafting increased by an increase in acrylamide concentration. Maximum grafting was obtained at 7 mi...
متن کاملImmobilization of Rhizomucor miehei Lipase on High Density Polyethylene
Immobilization of Lipase produced from Rhizomucor miehei on HDPE fine powder was investigated. As compared to an aqueous system, immobilization in a non-aquous organic medium such as n-hexane was not successful and caused enzyme denaturation. Prewetting the support with ethanol increased the immobilized protein and enzyme activity as much as 31% and 34%, respectively. The maximum immobilized a...
متن کاملCatalytic conversion of waste low density polyethylene into fuel oil
Waste Low density polyethylenes (LDPE) represent a source of energy and valuablechemicals, were pyrolysed catalytically in a batch reactor under atmospheric pressure. Calciumcarbide was used as a catalyst to explore its effect on pyrolysis product distribution. The effect oftemperature, amount of catalyst and time on the yields of the pyrolysed products wasinvestigated. The effect of catalyst o...
متن کاملOxygen-barrier films based on low-density polyethylene/ ethylene vinyl alcohol/ polyethylene-grafted maleic anhydride compatibilizer
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)...
متن کاملSpace Charge Behavior in Low-Density Polyethylene
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 ...
