✦ Synopsis

Poly(butylene terephthalate) (PBT), a thermoplastic polyester, was melt blended with acrylonitrile-butadiene-styrene (ABS) terpolymer using styrene-maleic anhydride (SMA) as the compatibilizer. The PBT : ABS ratio was fixed at 70 : 30 by weight and weight percent (wt %) of SMA was varied as 2.5, 5, and 7.5. The effect of variation of the SMA percent in the blend was studied by calculating and comparing the theoretical tensile strength values with the experimental ones. The adhesive strength (s) and the interaction parameter ( I) were also determined.
