We have fabricated three-layer films, comprising a varying content of ethylene–vinyl alcohol copolymer (EVOH) as the internal layer and blends of low-density polyethylene (LDPE) and low-density ethylene grafted with maleic anhydride (LDPE-g-MAH) as the external layers, by a coextrusion blown-film process. We chose to use blends to promote the adhesion between EVOH and LDPE and to reduce the num...

Two sample sets of low density polyethylene (LDPE) were investigated and differentiated via comprehensive analysis their microstructures with specific emphasis on branching.

This paper presents the preparation and mechanical properties of compatibilized compositionally graded Polyethylene/ low density polyethylene (LDPE)/ modified montmorillonite (MMT) nanocomposites prepared by solution and melt mixing techniques. Use of polyethylene glycol as compatibilizer improves compatibility of modified montmorillonite and low density polyethylene.  Comparisons between two t...

The influence of different additives: high density polyethylene (HDPE), low density polyethylene (LDPE) and TiO2 nanoparticles on the polyethylene terephthalate (PET)–rubber nanocomposite interface was investigated. The composites obtained by compression moulding from tire rubber and PET bottles’ waste were partially heterogeneous and partially compatible, as confirmed by the FTIRmeasurements. ...

Simultaneous thermogravimetry-mass spectrometry studies of a pyrolytic decomposition of mixtures of different plastic wastes/coking coal were carried out. The investigation was performed at temperatures up to 1000oC in a helium atmosphere under dynamic conditions at a heating rate of 25 oC/min. Five thermoplastics, commonly found in municipal wastes: low density polyethylene (LDPE), high densit...

Plastics wastes from a municipal solid waste (MSW) plant have a high-energy content and are suitable for fuel generation. Thermal cracking is one of the possible ways to obtain petrochemical feedstock from polymer wastes. Municipal waste plastic of LDPE conversion to kerosene grade fuel experiments were carried out under atmospheric conditions at temperatures between 150 ̊C and 420 ̊C. Low densit...

Low Density Polyethylene (LDPE) is produced by free radical polymerization. Industrially, LDPE polymerization process is usually carried out in a continuous mode (tubular or autoclave reactors) at high pressures (1300-3400 atm) and temperatures (50-340 0 C). LDPE exhibits a number of desirable properties, including high tensile strength, flexibility, high impact resistance, low crystallinity, l...

An innovative way to fix preformed nanocrystalline TiO(2) on low-density polyethylene film (LDPE-TiO(2)) is presented. The LDPE-TiO(2) film was able to mediate the complete photodiscoloration of Orange II using about seven times less catalyst than a TiO(2) suspension and proceeded with a photonic efficiency of approximately 0.02. The catalyst shows photostability over long operational periods d...

In this work plasma immersion (PI) was applied to Low Density Polyethylene (LDPE) and Polyethylene Terephtalate (PET) to improve their characteristics for food packaging. The effects of plasma composition were investigated by comparing treatments using N2 and SF6. Different treatment times were used at a total reactor pressure of 1.33 Pa composed by a steel vacuum chamber containing two interna...

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 minute...
