Flow properties of low density/linear low density polyethylenes
Polymer Engineering & Science, 1986AbstractRheological data have been collected both in shear and non‐isothermal elongational flow on three different types of blends, made from one low density polyethylene sample and three linear low density polyethylene samples.In addition to the flow curves, data are presented on the extrudate‐swell phenomenon, on the instability arising in capillary ...

Thermal fractionation and identification of low-density polyethylenes
Journal of Applied Polymer Science, 1996In the present publication, a method to identify and distinguish between different types of low-density polyethylene based on thermal fractionation and FTIR analysis is described. It was shown that during thermal fractionation four to seven endothermic peaks are obtained as opposed to one or two peaks obtained during regular differential scanning ...

Predictive control of a low density polyethylene plant
2001 European Control Conference (ECC), 2001The paper aims to present the possibilities of controlling a multizone tubular reactor for producing low-density polyethylene using the Model Based Predictive Control (MBPC) strategy, specifically Extended Predictive Self-Adaptive Control (EPSAC) approach.

AbstractMelting and crystallization phenomena in blends of a linear low‐density polyethylene (LLDPE) (ethylene butene‐1 copolymer) with a conventional low‐density (branched) polyethylene (LDPE) are explored with emphasis on composition by differential scanning calorimetry (DSC) and light scattering (LS). Two endotherms are evident in the DSC studies of

Journal of Applied Polymer Science, 1997
A linear low-density butene copolymer, of overall branch content 3 mol %, has been blended with a low-density polyethylene. The low-density polyethylene has an overall branch content of 5 mol %, including both long and short branches. The two materials were blended in a wide range of compositions and the phase behavior investigated using indirect ...

Photochemistry of low‐density polyethylene–montmorillonite composites
Journal of Applied Polymer Science, 2008AbstractPhoto‐oxidation at the exposed surfaces of low‐density polyethylene/montmorillonite composites was analyzed with attenuated total reflection/Fourier transform infrared spectroscopy. It was found that the clay particles were dispersed but not exfoliated in the polymer matrix.

Biodegradable Low Density Polyethylene
Progress in Rubber, Plastics and Recycling Technology, 2008LDPE in its unmodified form is not biodegradable. When it is compounded with additives or plasticizers, it is affected by microorganism in various degrees. Low Density Polyethylene film grade was compounded with butyl stearate, cottonseed oil, dioctyl phthalate, epoxidized soya bean oil, linseed oil, soya bean oil, groundnut oil and general-purpose ...
