摘要: Blends of polypropylene (PP) and low-density polyethylene (LDPE) may contribute to make recycling more economically attractive. The aim this work was PP/LDPE blends (0/100, 25/75, 50/50, 75/25 100/0 w/w) via injection molding carried out under various temperatures evaluate their tensile impact properties. yielded stress–strain curves very dependent on composition, especially regarding elongation at break the presence necking. An irregular behavior for 50/50 w/w blend is reported. Nevertheless, a linear variation yield strength elastic modulus with composition observed. also processing temperature. Addition 25% LDPE PP result in similar degradation its mechanical properties that caused by a1 08C temperature increase. Statistical analyses proved valuable when reporting results concerning blends. q 2005 Elsevier Ltd. All rights reserved.
