الملخص الإنجليزي
The thesis involved preparation of polymer blend as two systems, the first PS/ABS prepared by single screw extruder, the second PS/SBS prepared by Haake PolyDrive extruder.
Different composition ratios were used with the aim of arriving at the best physical blending percentage In order to study the influence of blending on the mechanical properties, thermal properties and morphology several tests are performed including (tensile, impact resistance, Differential scanning calorimetry (DSC), optical microscopy and scanning electron microscopy).
The results from this work show that the mechanical properties for blend system PS/ABS at compositions 70/30, 60/40 and 50/50 have mechanical properties mach better than the pure constituents.
The mechanical properties for the blend system of PS/SBS, dependent on the amount of SBS content, indicate in general it nearly obeys rule of mixtures.
The (DSC) test for blend system of PS/ABS gives good indication of improving state of miscibility for most blend ratios; there is only one glass transition temperature between the two values for pure polymers.
Also the DSC results for blends system of PS/SBS give good indications of improving state of partial miscibility.
The optical microscope and SEM results for both systems fully support the results obtained from the mechanical properties.
The FTIR results for PS/ABS blend system show that the PB phase in pure ABS has a cis configuration and these configurations change from cis to trans for all blend ratios.
