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...

Catalytic 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...

Evaluation of continuous and discrete melting endotherms in determination of structural heterogeneities in Ziegler-Natta catalyzed linear low density polyethylene

Ethylene / 1-butene copolymers at different comonomer levels were synthesized using Ziegler-Natta catalyst to evaluate the applicability of thermal fractionation methods in predicting chemical composition distribution (CCD). The continuous melting endotherms by DSC were converted to continuous CCD, and the average comonomer contents were compared with NMR results. DSC underestimated comonomer c...

Pervaporation (PV) Separation of Methanol/Methyl Tert-butyl Ether Mixtures in Low Permeate Pressure Conditions

Recently, pervaporation separation processes have gained much attention in the separation of azeotropic and close boiling point organic-organic mixtures due to its high separation efficiency, economy, safety, and energy saving potentials. In this work, the effects of experimental factors such as feed composition and operating temperature on the performance of a commercial poly vinyl alcohol mem...
