Abstract Due to the excellent insulation performance, ethylene-propylene-diene monomer (EPDM) is used as cable accessories. To obtain EPDM materials with high dielectric breakdown strength (DBS), special polar molecules and chemistry grafting/crosslinking technique are in this paper. In paper, we choose Maleic anhydride (MAH) an additive introduce deep traps, which generates increase strength(D...

Maleic anhydride-grafted-polyethylene was dynamically cross-linked via reactive melt blending with 4,4?-dithiodianiline. Thermal and mechanical properties of polyethylene vitrimers different cross-linking density were investigated. The results indicate that the degree crystallinity decreased increasing density. This behavior directly related to short-term long-term properties: showed a decrease...

Aim of study: In this study, the effect lignocellulosic filler and coupling agent amount on physical mechanical properties produced sugar beet pulp/LDPE composites were researched.
 Material methods: Wood-plastic using compression molding method. The (maleic anhydride grafted polyethylene) (density water uptake analyses) (tensile strength, tensile modulus, elongation at break, flexural imp...

Iron oxide nanoparticles (NPs) with a diameter 21.6 nm were coated with poly(maleic acid-alt-1-octadecene) (PMAcOD) modified with grafted 5,000 Da poly(ethyelene glycol) (PEG) or short ethylene glycol (EG) tails. The coating procedure utilizes hydrophobic interactions of octadecene and oleic acid tails, while the hydrolysis of maleic anhydride moieties as well as the presence of hydrophilic PEG...

Using Electrostatic Spray Coating Technique, Polypropylene Powder (EPD 60R) was applied on carbon steel substrates at room temperature. In order to obtain a uniform coating, steel substrates with powder coatings were heated in a vacuum oven at various temperatures up to 250° C for various periods of time up to 45 min and a pressure of 200 mb. The coatings produced had thicknesses of around 470 ...

Polypropylene/babassu thermoplastic starch (PP/TPS, 70:30 w/w) blend sheets were prepared as an alternative material to use in disposable packaging, reducing the negative environmental impact of synthetic polymer. Three different carboxyl acids: palmitic (PP/TPS/P), citric (PP/TPS/C), and stearic (PP/TPS/S), used natural compatibilizing agents (NCA) compared conventional maleic anhydride (PP/TP...

Oxidation of 3- and 4-pentafluorosulfanyl-substituted anisoles and phenols with hydrogen peroxide and sulfuric acid provided a mixture of SF5-substituted muconolactone, maleic, and succinic acids. A plausible mechanism for the formation of the aliphatic SF5 compounds was presented and their chemical reactivity was investigated. SF5-substituted para-benzoquinone was synthesized; its oxidation le...
