Beschreibung
Zusammenfassung:	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. 提供一种层状硅酸盐，其具有片晶形式的层状结构，并且在片晶之间包括插层剂，其中插层剂是分子量为274至30,000g/mol的聚酯，并且其中层状硅酸盐不是通过离子交换改性的层状硅酸盐。还提供了一种聚合物纳米复合材料，其包括聚对苯二甲酸乙二醇酯(PET)聚合物以及上述层状硅酸盐，以及制备插层层状硅酸盐和PET纳米复合材料的制备方法。PET纳米复合材料特别适用于包装，特别是用于食品和饮料包装。
