It is estimated that 60 to 70% of LLDPE enters the market as blends (Utracki 1989a), primarily with other members of the polyolefin family, e.g., LDPE or polypropylene (PP). Despite the long history of polyethylene (PE) blending and its widespread use, many questions about the homogeneity of such blends, with obvious implications for thermodynamics and for the rheology, are still not answered t...

Effects of light intensity gradient on development of intricate hierarchical morphology of semicrystalline polyethylene oxide (PEO) and photoreactive diacrylate (DA) blends undergoing photopolymerization-induced crystallization have been demonstrated experimentally and theoretically. The melting temperature of PEO was found to decline upon addition of DA monomer. A solid-liquid phase diagram ha...

Dissipative particle dynamics (DPD), a mesoscopic simulation approach, is used to investigate the effect of volume fraction of polyethylene (PE) and poly(l-lactide) (PLLA) on the structural property of the immiscible PE/PLLA/carbon nanotube in a system. In this work, the interaction parameter in DPD simulation, related to the Flory-Huggins interaction parameter χ, is estimated by the calculatio...

The influences of short chain branching (SCB) and molecular (Mw) weight of low density polyethylene (LDPE) on the solid state properties of polypropylene (PP)-LDPE blends were investigated by mechanical and thermal techniques. DSC analysis of all blends exhibit a double melting peak at all compositions studied thus suggesting that both PP and LDPE crystals exist separately in the solid state. I...

Blends of acrylonitrile butadiene rubber/high density polyethylene (NBR/HDPE) compatibilized by Chloroprene rubber (CR) were prepared. A fixed quantity of industrial waste such as marble waste (MW, 40 phr) was also included. The effect of the blend ratio and CR on cure characteristics, mechanical and swelling properties of MW-filled NBR/HDPE blends was investigated. The results showed that the ...

COMPUTING IN SCIENCE & ENGINEERING terials, surfactants, and so on. While we can perform atomistically realistic simulations in special cases (molten polyethylene at high temperatures4 or polyethylene crystals in the orthorhombic phase5), these calculations are cumbersome due to potential complexity, and phase transition studies are out of reach. This is even more true for polymer blends, where...

AIMS The following polymers were developed: polyethylene (PE), a PE and polyethylene oxide (70% PE and 30% PEO; PE + PEO) blend, PE and nisin (PE + nisin), PE, nisin, and EDTA (PE + nisin + EDTA), and PE + PEO with nisin (PE + PEO + nisin). METHODS AND RESULTS Of the polymers tested, PE and PE + PEO did not exhibit any antimicrobial activity against Brochothrix thermosphacta (BT); however, PE...

The presence of a polyethylene (PE) fraction in recycled polypropylene (PP) will influence the processing as well mechanical and thermal properties polypropylene. objective this work has been to compare methods used determine PE PP, establishing calibration curves for each method. Plastics waste be mix different grades – homopolymers copolymers. It therefore tested how specific material affect ...

In this work, blends of polyethylene glycol (PEG) and poly(methyl methacrylate) (PMMA) with nanosponge-like porous structure are fabricated by a solution phase separation method, subsequently the nanosponge-porous also applied for high performance triboelectric nanogenerator (TENG). The features controlled varying polymer concentrations PEG/PMMA ratios. A TENG device made PEG-PMMA blend convex-...

In this work, the percentage of polyethylene (PE) and polypropylene (PP) blend is controlled at 50:50 to make composite by forming a co-continuous structure with hexagonal boron nitride (h-BN). The h-BN wrapped thermoplastic elastomer styrene-ethylene-propylene-styrene (SEPS). This approach enables localized distribution interface PE/PP SEPS phases, allowing construction heat conduction path in...
