Abstract
Solubility characteristics of bisphenol A polycarbonate, acrylonitrile -butadiene-styrene and their blends are studied in different solvents. A computer program known as 'spherical volume of solubility' is used to determine total and partial solubility parameters of the polymers a nd their blends. The solubility parameters calculated from group contr ibution techniques are compared with the computed data. Using Bagley's approach, the composition of a blend with synergy is predicted. Mecha nical properties of the blends are found to be in good agreement with the predictions made from the solubility studies. (C) 1997 Elsevier Sc ience Ltd.
