mechanical properties of wood/plastic composites manufactured by polyethylene and polypropylene blends (pp/hdpe) were studied. the sebs (styrene-ethylene butylene-styrene) and epdm (ethylene-propylene diene monomer) were used as compatibilizers to improve the compatibility and miscibility of the interface between hdpe and pp phases. the sawdust and polymers were compounded using an internal mix...

Kenaf polypropylene composites with high fiber load of 85 wt% were produced using glycerine as a processing aid and maleic anhydride-grafted (MAPP) compatibilizer/coupling agent. Commercially available MAPPs different molecular weights anhydride contents used to determine what properties the important achieve mechanical these highly filled composites. A homo-polymer random-polymer, compared mat...

Adding acid-modified resin compatibilizers is essential for plastic composites reinforced with carbon-neutral cellulosic filler. Researchers have measured the efficacy of adding a compatibilizer in context mechanics. However, it necessary to microscopically clarify how actually works quality control and further expansion applications. In this review, author first describes situation presents is...

Poly(lactic acid) (PLA) was melt mixed in a laboratory extruder with poly(butylene adipate-co-terephthalate) (PBAT) and poly(butylene succinate) (PBS) in the presence of polypropylene glycol di glycidyl ether (EJ400) that acted as both plasticizer and compatibilizer. The process was then scaled up in a semi-industrial extruder preparing pellets having different content of a nucleating agent (LA...

The copolymer VAMA was synthesized from vinyl acetic and maleic anhydride. A new all-polymeric blend with a high dielectric constant (ε) has been developed by blending polyvinylidene fluoride (PVDF) with vinyl acetic-maleic anhydride modified polyamide (PA66-g-VM). The blend shows high dielectric constants (εblend = 20) and excellent mechanical properties. The SEM investigations suggest that th...

Melt free-radical grafting reactions between ethylene-propylene-dieneterpolymer (EPDM) and glycidyl methacrylate (GMA) were investigated in a batch mixer (170°C, 60rpm). Effect of dicumylperoxide (DCP) initiator and GMA functionalizing monomer concentrations was studied on the grafted EPDM characteristics. Titration results indicated an increase in the graft degree (GD) and gel content (GC) val...

The influence of quartz (silicon dioxide) content on main physical and mechanical properties composites based low density polyethylene is considered. It shown that the introduction a compatibilizer – copolymer high-density with maleic anhydride into composition improves compatibility mixed components. use synthesized wax as plasticizer made it possible to significantly improve deformability hig...

Poly(vinyl chloride) (PVC) is considered one of the most versatile polymers due to its interaction with different additives. On other hand, binary sulfides have wide applications as zinc sulfide (ZnS), first discovered semiconductors. This study aims synthesize a nanocomposite material containing nano ZnS in PVC matrix surfactant compatibilizer agent evaluate optical and electrical properties w...
