Characterization of EPDM/atactic polypropylene blends

Characterization of polypropylene–polyethylene blends by temperature rising elution and crystallization analysis fractionation

The introduction of single-site catalysts in the polyolefins industry opens new routes to design resins with improved performance through multicatalyst-multireactor processes. Physical combination of various polyolefin types in a secondary extrusion process is also a common practice to achieve new products with improved properties. The new resins have complex structures, especially in terms of ...

Tensile and impact behavior of polypropylene/low density polyethylene blends

Blends of polypropylene (PP) and low-density polyethylene (LDPE) may contribute to make recycling more economically attractive. The aim of this work was to make PP/LDPE blends (0/100, 25/75, 50/50, 75/25 and 100/0 w/w) via injection molding carried out under various injection temperatures and to evaluate their tensile and impact properties. The blends yielded tensile stress–strain curves very d...

Morphology and Mechanical Properties of Binary Blends of Polypropylene with Statistical and Block Ethylene-Octene Copolymers

In the present work, statistical (EOCs) and block (OBCs) ethylene-octene copolymers, with similar densities and crystallinities, were used as impact modifiers of isotactic polypropylene (iPP), and the toughening effects of these two types of elastomers were compared. The viscosity curves of EOCs were similar to those of OBCs with equivalent melt flow rate (MFR), enabling a comparison of the vis...
