Abstract: the effects of stabilizer and plasticizer on the thermal stability of blend of polyvinyl chloride) (PVC) and acrylonitrile-butadiene-styrene(ABS) were studied via thermogravimetric analysis and Congored method. Both stabilizer and plasticizer DAP improved thermal stability of PVC/ABS with a cost of mechanical properties. The dosage of the stabilizer and DAP should be limited below 5 and 15 phr, respectively. DC}P improved not only the processability, but also the dispersion of stabilizer in the blends.
