Abstract
Blends having a high molding fluidity and flowability and high thermoresistance comprising: (a) at least one vinyl-aromatic thermoplastic polymer; and (b) at least one copolyester having a melting point lower than the molding temperature of the thermoplastic polymer (a), and preferably lower than 200.degree. C., a melt viscosity, at 232.degree. C., lower than 50 Pa.S., and obtained from at least one bicarboxylic aromatic acid, at least one aliphatic bicarboxylic acid, and at least one glycol.
