“…Grafting of MA onto non-polar polymers increases the hydrophilicity of the polymer surface. Therefore, the maleated polymer can be used as a main component in a reactive blending process [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. The grafting of MA onto NR has been commonly done in the molten state by using shearing action in the presence or absence of peroxide.…”

The direct incorporation of ground tire rubber (GTR) as a waste rubber into a virgin polymer matrix causes a remarkable reduction in its mechanical and performance properties. In this work, maleic anhydridegrafted natural rubber (MA-g-NR) was employed as a compatibilizer to improve the interaction between a natural rubber (NR) matrix and GTR. The effect of MA-g-NR on curing characteristics, rheological behavior, morphology, and performance properties of the NR-GTR blend was studied using an oscillating disk rheometer, rheomechanical spectroscopy (RMS), scanning electron microcopy (SEM), and tensile and abrasion testing. The obtained results by RMS and SEM tests revealed better adhesion between NR and GTR in the presence of MA-g-NR. Using up to 8 parts of MA-g-NR caused an increase in the curing rate index, and a remarkable increase in mechanical properties and abrasion resistance was observed, which was comparable to or even better than the virgin vulcanizate.
