Abstract
The present invention relates to polyester-platelet particle composite compositions comprising about 0.01 to about 25 weight percent platelet particles dispersed in at least one polyester wherein said composition has an I.V. of greater than about 0.55 dl/g, low shear melt viscosity greater than about 30,000 poise and a gas permeability which is at least 10% lower than that of unmodified polyester and processes for producing same.
