A three-step multiscale modeling approach to predict and thus control polymer properties, such as flow behavior linear well non-linear rheology, based on polymerization conditions, is developed applied for long-chain branched low-density polyethylene (LDPE). The consists of i) a deterministic kinetic model the description conversion average characteristics, ii) hybrid stochastic Monte Carlo pol...

Graft copolymerization of binary mixtures of vinylene carbonate (VCA) and N-vinyl-Nmethylacetamide (VIMA) onto low density polyethylene (LDPE) films was studied by the mutual y-irradiation technique. Sufficient amounts of functionally active VCA groups could be grafted onto the surface and the hydrophilicity of the surface was also improved. The grafting of VCA onto polyethylene films in the bi...

Background: Pseudomonas sp. AKS2 can efficiently degrade low-density polyethylene (LDPE). It has been shown that this degradation of LDPE by AKS2 is correlated to its ability to form biofilm on the polymer surface. However, the underlying mechanism of this biofilm-mediated degradation remains unclear. Since bioremediation potential of an organism is related to its adaptability in a given enviro...

Injection moulding is one of the most popular polymer processing methods due to its high production rate as well as its ability to produce very intricate geometries at very cheaper cost and within few seconds. There are several flaws which occur while producing plastic parts by Injection moulding, like warpage, shrinkage, flash, sink marks etc. Shrinkage is one of the most critical problems whi...

This study aims to investigate the effect and possibility of using waste plastic as a sustainable cost-effective polymer modify bitumen binders. Different types have been used in this modification, including polyethylene terephthalate (PET), high-density (HDPE), low-density (LDPE). The modification targets physical characteristics, rheological properties, binders’ resistance ageing. Both long- ...

The influence of a typical prooxidative additive, cobalt stearate, on the thermal stability, degradation kinetics and lifetime of low-density polyethylene (LDPE) was investigated using non-isothermal thermogravimetric analysis (TGA) in both nitrogen and air atmosphere. The derivative thermogravimetric (DTG) curves indicate single stage and multistage decomposition process in nitrogen and air at...

The dispersion, morphology and crystallization kinetics of low density polyethylene (LDPE) octakis(noctadecyldimethylsiloxy)octasilsesquioxane (POSS) nanocomposite blends was investigated. Novel octakis(dimethylsiloxy)octasilsesquioxane (Q8M8) molecules were octafunctionalised with octadecyl alkyl-chains (Q8C18) and blended with 0.25-10 wt% loadings into a commercial LDPE. Time-resolved Smallan...

Among the various requirements that high voltage direct current (HVDC) insulation materials need to satisfy, sufficiently low electrical conductivity is one of most important. The leading commercial HVDC material currently an exceptionally clean cross-linked low-density polyethylene (XLPE). Previous studies have reported DC-conductivity (LDPE) can be markedly reduced either by including a fract...

Indian gooseberry (Emblica officinalis Gaertn.) is an indigenous important hardy underutilized fruit crop of India. The objective the present investigation was to evaluate effect Modified Atmospheric Packaging- Low Density Polyethylene (MAP-LDPE) on storage life and quality (physico-chemical attributes) different cultivars Aonla fruits up 12 days. Physico-chemical attributes such as Physiologic...
