Welding experiments using a double cantilever beam test geometry for a miscible poly(styrene-coacrylonitrile)/ poly(methyl methacrylate) (SAN/PMMA) system showed the expected linear increase of the fracture toughness, Ga, with the root of annealing time. For immiscible pairs of PMMA and SAN it was found that G a increases linearly with the equilibrium interfacial thickness or, equivalently, to Z- 1/2, Z being the Flory interaction parameter
