Abstract
There is disclosed a blend of certain polyesters and polymers that are miscible with polystyrene, such as polyphenylene oxide. The blend is characterized by the presence of a compatibilizing amount of a copolymer having repeating units derived from an aromatic vinyl compound monomer and a vinylphenol monomer. The polyester is thermoplastic and is characterized in that the diacid component of the polyester includes aromatic groups and the diol component comprises at least about 20 percent by weight of a noncyclic, aliphatic diol.
