dc.description.abstractTri component of neat poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT) and neat acrylonitrile butadiene styrene (ABS) were melt blended over the different composition ranges using a single screw extruder. Different possible combinations of di and tri component polyester/polyester (PET/PBT) and polyester/polyester/elastomer (PET/PBT/ABS) blends were synthesized using acrylonitrile butadiene styrene grafted maleic anhydride (ABS-g-MAH) as the compatibilizer. Di component blends of PET/ABS & PBT/ABS were also synthesized. The ABS fraction in all studies was kept constant at ten weight percent. The rheological, mechanical and thermal behavior of all the neat polyesters, ABS and the di and tri component blends were investigated. The neat polyesters and ABS showed the highest values for viscosity, storage and loss modulus compared to the di and tri component blends. Mechanical analysis revealed that the tensile strength, tensile modulus and percentage elongation of the neat polyesters and ABS was the highest compared to the di and tri component blends. From the DSC analysis it was noted that on blending the di component blends in the presence of a compatibilizer, the melting temperature (Tm) and glass transition temperature (Tg) were shifted to lower temperatures compared to the parent samples. But in case of tri component blends the shift in Tm and Tg is not as much as that of the di component blends. This led to a conclusion that the amount of interface formed on blending a di component with a compatibilizer is less than when a tri component compatibilized blend is formed.en_US
