Fibers spun by melt spinning of binary and ternary polypropylene/ polyethylenetherephthalate blends have been produced and characterized in order to investigate the effect of a compatibilizer on their morphology and mechanical properties. The compatibilizer was a maleic anhydride-functionalized rubber copolymer. The effect of the compatibilizer was well evident in the isotropic state, as the mo...

Polypropylene owing to its apolar nature suffers from compatibility problems with clay, which is partially polar even after the surface modification with alkyl ammonium ions. To circumvent this limitation, polypropylene nanocomposites have been synthesized by using two methodologies: a) partial polarization of the matrix by the addition of low molecular weight compatibilizer which owing to its ...

pp/pep blends, because of different solubility factors, are incompatible. the aim of this research was to use pp-g-ma compatibilizer in a two-component blend. after preparing this compatibilizer in internal mixer and investigating different parameters on producing process, optimum compatibilization was obtained. pp/pet (60/40) blend fibers with different percentages of this compatibilizer in tw...

In this study, effect of MAPE (maleic anhydride polyethylene) as the compatibilizer on the mechanical properties of wood-flour polyethylene composites has been investigated by using Dynamic Mechanical Analysis (DMA). Composites were made at 25% and 50% by weight fiber contents and 1% and 2% compatibilizer respectively. Controls were also made at the same fiber contents without the compatibilize...

The blending of aliphatic polyolefins and aromatic poly(ethylene terephthalate) (PET) based on different intrinsic viscosities (IV) was conducted in a torque rheometer. The comparison of blend components in terms of low density polythene (LDPE) and polypropylene (PP) in blending with PET was investigated, and the effects of the IV and proportion of PET on polymer blends are discussed in detail....

Immiscible homopolymers are often blended mechanically to obtain blends with properties significantly superior to those of the component polymers. The creep recovery of such blends was studied in the previous paper, henceforth referred to as I. Surface-active compatibilizers are commonly added to such blends to improve blending of the immiscible phases and to improve the mechanical properties o...

The rheological properties of blends of immiscible homopolymers have received much attention in recent years (Tucker and Moldenaers 2002). Several publications have been devoted to examining the relationship between the rheology and morphology of two-phase blends. A key strategy employed by many researchers was to conduct experiments on ‘‘model’’ blends that were comprised of rheologically-simp...

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...

the purpose of this study was to evaluate effects of nano-clay particles and oxidized polypropylene as compatibilizer on the decay resistance of wood plastic composite against coriolus versicolor fungi. in order to provide oxidized polypropylene as compatibilizer, polypropylene was oxidized in the presence of air oxygen in 2 hours by internal mixer. afterwards, wood fibers, polypropylene, nano-...

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...
