Compositions comprising a polyester resin and a polyamide derivednfrom a dicarboxylic acid with 6-22 carbon atoms and from m-xylylenendiamine having high-level gas barrier properties, obtained by mixing in thenmelted state the polyester resin premixed with a dianhydride of antetracarboxylic acid and the polyamide, operating under conditions such asnto render the polymeric components rheologically compatible each other.nThe compositions are suitable for preparing containers and biaxially-orientatednfilms. |
