Manufacturing and compatibilization of binary blends of polyethylene and poly(bulylene succinate) by injection molding

<p class="JARTEAbstract">In this study was analyzed the effect of three different compatibilizers polyethylene-graft-maleic anhydride (PE-g-MA), unmodified halloysite nanotubes (HNTs), and HNTs treated by silanization with (3-glycidyloxypropyl) trimethoxysilane (GLYMO) (silanized HNTs) in blends bio-based high-density polyethylene (bioPE) poly(butylene succinate) (PBS) a weight ratio (70/30). Each compatibilizer added proportion (3 phr regarding PBS). Standard samples were obtained extrusion subsequent injection molding. The analyzes performed mechanical tests, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), dynamic thermal (DMTA), field emission electron microscopy (FESEM), wettability (θ<sub>w</sub>). Results suggest that addition modified allowed to obtain better properties than compatibilized PE-g-MA, due it contributes improvement bioPE/PBS blend, for instance, tensile modulus elongation at break increase about 8% 13%, respectively. In addition, determined through FESEM images silanized particles dispersed over matrix, which fact contribute enhance properties. TGA showed delay degradation temperature uncompatibilized blend. While DMTA indicated reduction mobility chains HNTs. Therefore, successfully blends, constitutes an interesting option develop new sustainable polymers.</p>
