Solution blending of polystyrene (PS) and natural rubber (NR) was carried out in toluene and chloroform to determine the compatibility. Experimental evidence for the compatibility of these blends was derived from viscometric and phase‐separation studies. The viscometric method was based on the intrinsic viscosities of transfer of polymer in pure and “mixed” solvents. The compatibility of these blends based on the heat of mixing was also examined theoretically. All the experimental and theoretical evidence show that the blends are incompatible at the compositions studied. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 77: 880–889, 2000
