Abstract

Blends of both polystyrene and of poly (a-methylstyrene) with poly(styrene-stat-a-methyl styrene) samples of varying composition have been studied using differential scanning calorimetry to determine the limits of miscibility with respect to composition and molecular weight. From an analysis of the results a value for the styrene-a-methylstyrene segmental interaction energy density, B_s-ms, was determined and compared with other estimates of this quantity. Discrepancies with the results of other workers are discussed in terms of possible solvent effects derived from the blend preparation. Compared to the molecular weight limited miscibility of polystyrene blended with poly(a-methylstyrene), enhanced miscibility of both polystyrene and poly(a-methylstyrene) with the copolymers is demonstrated. © 1992.
