摘要：

The intrinsic viscosities of blends of bisphenol-A polycarbonate and poly(hexamethylene sebacate) have been measured in chloroform as a function of blend composition for a variety of molecular weight species. The compatibility of the polymer blend mixtures is characterized by the parameter Δb, from the Krigbaum and Wall theory. Using Tg of the blend as a measure of bulk solid-state compatibility, a correlation is obtained with the Krigbaum and Wall parameter Δb for each of the molecular weight pairs studied. Slopes of the correlation are invariant, as expected, as the chemical composition is the same for the different molecular weight pairs studied.
