Abstract A commercial polyarylate (PAr), a copolyester of Bisphenol‐A with 50 percent terephthalate‐50 percent isophthalate, has been characterized by means of a combination of gel permeation chromatography and viscometry. It has been studied as first component of a series of polymer blends. The presence of either one glass transition temperature ( T g ) or two has been used as a criterion to determine the miscibility of each blend. In some cases, the possible incidence of transesterification reactions has been considered.
