The difference in polarity of recycled high density polyethylene (rHDPE) and ethylene vinyl acetate (EVA) blends leads to poor mechanical properties (Atul Rajan, 2013). Present works aim at finding the effects of maleic anhydride on the mechanical, morphological, and water resistance properties of rHDPE/EVA/ESP blends. It is shown that there is a significant improvement on tensile strength, interfacial adhesion between components, and water absorption resistance of adding maleic anhydride (MA) to rHDPE/EVA/ESP blends. This study may suggest that the MA can act as compatibilizer to enhance the interfacial interaction between the rHDPE and EVA matrix in the rHDPE/EVA/ESP composites.

This paper presents the study on the effects of benzyl urea (BU) on the mechanical, morphological, and water absorption properties of recycled high density polyethylene/ ethylene vinyl acetate/ eggshell (rHDPE/EVA/ESP) composites. The results indicated significant improvement in the tensile strength and modulus of elasticity of the compatibilized composites due to better interfacial adhesion between the rHDPE and EVA. The water resistance properties were increased by the addition of the BU to the rHDPE/EVA/ESP composites. This study may suggest that BU can act as compatibilizer to enhance the interfacial interaction between the rHDPE and EVA matrix in the rHDPE/EVA/ESP composites.

The effect of polyethylene grafted maleic anhydride as a compatibilizer on the tensile properties, and swelling behavior of recycled high density polyethylene/ethylene vinyl acetate/ waste tyre dust (r-HDPE/EVA/WTD) composites was studied. r-HDPE/EVA/WTD composites with different tyre dust loading and the addition of polyethylene grafted maleic anhydride (PEgMAH) were prepared with Brabender Plasticorder at temperature of 160°C and rotor speed of 50 rpm. The result indicated that r-HDPE/EVA/WTD/PEgMAH composites exhibit higher tensile strength, modulus of elasticity, and mass swell resistance than r-HDPE/EVA/WTD composites.

Taro powder (TP) filled composites based on recycled high density polyethylene (RHDPE)/ ethylene vinyl acetate (EVA) were prepared via melt blending method. Polyethylene-grafted-maleic anhydride (PE-g-MAH) was used as a compatibilizer to enhance interfacial bonding of RHDPE/EVA/TP composites. The effects of TP loading and the addition of PE-g-MAH on the tensile properties and thermal stability of RHDPE/EVA/TP composites were investigated and studied. Findings indicated that increased TP loading will reduce tensile strength and elongation at break while increasing the modulus of elasticity. The thermal stability of RHDPE/EVA/TP composites improved by increasing filler loading. With respect to both tensile properties and thermal stability, RHDPE/EVA/TP composites with PE-g-MAH performed better than the composites without the addition of compatibilizers.

This paper describes tensile properties, and morphology analysis of different composition of RHDPE and EVA blends were studied. The main goals are to describe the effect of Caprolactam as compatibilizer used to improve the compatibility between RHDPE and EVA. The RHDPE/EVA blends were prepared at 160°C and the rotor speed of 50rpm in an internal mixer. The tensile strength for RHDPE/EVA blends increased, while adding Caprolactam by 6phr in the blend formulation significantly improved the tensile properties. The SEM micrograph show a better interfacial adhesion between RHDPE and EVA phases for RHDEP/EVA/Caprolactam blends than RHDPE/EVA blends.

The compatibilized poly ethylene vinyl acetate copolymer (EVA)/high density polyethylene (HDPE) /organomodified montmorillonite (OMMT) blend nanocomposites were prepared in a co-rotating twin-screw extruder followed by injection molding. Montmorillonite clay was modified by octadecylamine and aminopropyltriethoxysilane to make it organophilic. Maleic anhydride grafted high-density polyethylene was used as a Compatibilizer. Nanoclay was added in different proportions to the selected EVA/HDPE blend composition. The concentration of nanoclay was varied from1 to 5 phr in the polymer blend. The resulting nanocomposites were evaluated in terms of their water absorption behavior. Moisture absorption behavior of compatibilized blends is lower than their corresponding blend. On adding the nanoclay the moisture absorption behavior of blend nanocomposites changed at 4 phr nanoclay loading.
