TLDR
In this paper, the dynamic and steady state behavior of metallocene linear low density polyethylene (m-LLDPE) blended with high-density polyethylen and with low-dense polyethylenes (LDPE), was measured in parallel plate rheometer at 160, 180, and 200 degrees C. The results were consistent with the rheological properties of these two series of blends.About:

Evaluation and simulation of silver and copper nanoparticle migration from polyethylene nanocomposites to food and an associated exposure assessment.
TL;DR: The potential migration of nanoparticles from PE composite packaging to a food material and the potential for simulation models to accurately capture this migration potential are highlighted; however, variable background levels of copper in the food matrix can make prediction more difficult for trace migration of nanocopper.

Rheological behavior of blends from a linear and a long-chain branched polypropylene
TL;DR: In this article, the authors investigated how the rheological behavior of a linear polypropylene is changed by blending with different amounts of a long-chain branched polypolypropylene.
Journal ArticleDOI
Effect of composition and comonomer type on the rheology, morphology and properties of ethylene-α-olefin copolymer/polypropylene blends
TL;DR: In this paper, the rheology, morphology, thermal and mechanical properties of blends containing low molecular weight polypropylene (PP) and metallocene-based ethylene-α-olefin copolymers (ECs) have been investigated.
Journal ArticleDOI
Rheological and thermal properties of blends of a long-chain branched polypropylene and different linear polypropylenes
TL;DR: In this paper, the effect of adding LCB-PP on the crystallinity, crystallization temperature, melting point, and rate of crystallization were studied using differential scanning calorimetry (DSC) and positive deviations from the Fox equation for the glass transition temperature, T g, were observed for the blends.
Journal ArticleDOI
Quantitative analysis of melt elongational behavior of LLDPE/LDPE blends
TL;DR: In this paper, the authors analyzed the shear and elongational data of linear (LLDPE) and branched (LDPE)-polyethylene polyethylene blends and showed that the strain hardening behavior of LLDPE/LDPEs is completely determined by the LDPE component.

Stereospecific Olefin Polymerization with Chiral Metallocene Catalysts
TL;DR: In contrast to heterogeneous Ziegler-Natta catalysts, homogeneous metallocene-based catalysts as discussed by the authors allow efficient control of regio-and stereoregularities, molecular weights and molecular weight distributions, and comonomer incorporation.

Effect of Molecular Structure on the Linear Viscoelastic Behavior of Polyethylene
TL;DR: In this paper, the effects of weight-average molecular weight (MW) and short and long chain branching on the linear viscoelastic behavior of polyethylene (and ethylene−α-olefin copolymers) are described.
