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.

Abstract Electron beam irradiation of Ethylene vinyl acetate, EVA (VA content 12, 28 & 45%) copolymer was carried out in presence of trimethylolpropane trimethacrylate (TMPTMA) and triallyl cyanurate (TAC) and the structure of the modified copolymers was determined with the help of IR spectroscopy and gel content measurements. The IR absorbance peak at 1640 cm−1 disappears at lower radiation dose indicating that the grafting and crosslinking reactions take place through double bonds. Some carbonyl groups are formed during irradiation. The concentration of carbonyl group increases with the radiation dose and the level of multifunctional monomers. The grafting level of TAC onto EVA determined from IR absorbance peak at 1565 cmx−1 remains almost constant with the variation of radiation dose and increases with TAC level. The gel content increases with radiation dose, but changes marginally with TMPTMA and TAC levels. The percent gel content increases linearly with vinyl acetate content in EVA.
