Polymer nanocomposites containing poly (ethylene terephthalate) reinforced with intercalated phyllosilicates

摘要

A phyllosilicate having a lamellar structure in the form of platelets and containing an intercalating agent between the platelets, wherein the intercalating agent is a polyester having a molecular weight of 274 to 30,000 g / mol, and phyllosilicate A phyllosilicate is provided wherein the salt is other than a phyllosilicate modified by ion exchange. Also provided are preparation processes for preparing polyethylene terephthalate (PET) polymers, polymer nanocomposites comprising the phyllosilicates described above, and intercalated phyllosilicates and PET nanocomposites. PET nanocomposites are particularly useful for packaging, particularly food and beverage packaging.
