Abstract
The invention provides methods for preparing composites of polyester and layered compounds. In one embodiment, the invention provides a method for preparing a composite of a poly(alkylene terephthalate) and a cation-modified layered compound via in-situ polycondensation in solvent. In another embodiment, composites are made with polyesters of average molecular weight of 10,000 g/mol or more by mixing the polyester and a layered compound in the presence of a solvent, such as ortho-dichlorobenzene.
