It is provided a phyllosilicate having a layered structure in the form of platelets and comprising an intercalating agent between the platelets, wherein the intercalating agent is a polyester of a molecular weight of 274 to 30,000 g/mol, and wherein the phyllosilicate is other than a phyllosilicate modified through ionic interchange. It is also provides a polymer nanocomposite comprising a polyethylene terephthalate (PET) polymer an the phyllosilicate mentioned above, as well as preparation processes for the preparation of the intercalated phyllosilicate and the PET nanocomposite. The PET nanocomposite is particularly useful for packaging, particularly for food and drink packaging.

Polymer nanocomposite comprising poly(ethylene terephthalate) reinforced with an intercalated phyllosilicate

The composition comprises a mixture of: i) poly(L-, D-lactide) homopolymer and, optionally, poly(&#x3b5;-caprolactone) homopolymer, and ii) poly(L-lactide) and poly(&#x3b5;-caprolactone) diblock copolymer, where said copolymer has a molar mass of the L-lactide block of 20,000 g/mol to 200,000 g/mol and a molar mass of the &#x3b5;-caprolactone block of 10,000 g/mol to 100,000 g/mol, with the molar ratio between the L-lactide block and the &#x3b5;-caprolactone block of 2:1. The invention also refers to the nanostructured material obtained from this composition that is characterised by a nanostructure of two mutually self-assembled phases, one phase being formed by a polymeric matrix of poly(L-, D-lactide) units and the other phase by poly(&#x3b5;-caprolactone) units self-assembled with the matrix and also its use for the manufacture of a plastic article in the form of a transparent film or thin sheet.
