This work studied the polymer blend of recycled polyethylene terephthalate from plastic bottles (RPET) and nylon 6 to improve the mechanical properties of polyethylene terephthalate. These polymers were incompatible, so reactive compatibilizer, ethylene/butyl acrylate/glycidyl methacrylate copolymers (EBM), was added to increase the compatibility of the polymer blend. The polymer blend was compounded with different EBM ratio at 1, 3 and 5 phr via twin-screw extrusion. The polymer blends were tested by FTIR, DSC, tensile and impact properties, and morphology. The addition of PA6 resulted in a change of the RPET crystallization and the addition of 3 and 5 phr. of EBM resulted in the formation of RPET crystals at lower temperatures. The tensile test showed that the addition of EBM in the increased quantity resulted in higher tensile strength and elongation at break. In addition, the morphology of the fracture surface of RPET/PA6 showed that the PA6 dispersed better with increasing EBM content. |
