Polyester nanocomposites with improved mechanical properties include melt-blending a mixture of fibrous clay, sodium salt, optionally at least one linear polyester oligomer and at least one polyester polymer; And optionally, solid phase polymerizing the nanocomposite composition, thereby increasing the polyester molecular weight. In addition, polyester nanocomposites can be prepared from melt-blended masterbatches containing a concentration of fibrous clay that is greater than the concentration of the desired fibrous clay in the final resin composition. |
