Comparative Study of the Flexural Strength and Impact Strength properties Between Two Types of the Ternary Polymer Blends

Compatibility is one of the major problems which effect on the characteristics of polymer blends. Therefore, in the current search Polypropylene Grafted Maleic Anhydride (PP-g-MA) was used to improved compatibility between the components of the binary polymer blends. So, two sets of ternary polymeric blends were prepared by melt-mixing method using double-screw extruder. The first group is containing on (polypropylene (PP): 1% (PP-g-MA): X% polymethylmethacrylate (PMMA), the second group consists of (PP: 1%(PP-g-MA): ultra-high molecular weight polyethylene (UHMWPE)). The blends, containing between 5 to 20% ratios of a third material (PMMA or UHMWPE) and 1% of compatibilizer material (PP-g-MA). Investigation the bending strength and impact strength was done for the prepared specimens. Study shown that, the polymer blends (PP: 1 %(PP-g-MA): X% PMMA) gained the higher properties in flexural strength, whereas the polymer blends (PP: 1% (PP-g-MA): X% UHMWPE) have got the higher values in impact strength and fracture toughness.
