Title (EN) POLYMER NANOCOMPOSITE COMPRISING POLY(ETHYLENE TEREPHTHALATE) REINFORCED WITH AN INTERCALATED PHYLLOSILICATE
(FR) NANOCOMPOSITE POLYMÈRE COMPRENANT DU POLYÉTHYLÈNE TÉRÉPHTALATE RENFORCÉ AVEC UN PHYLLOSILICATE INTERCALÉ
Abstract: front page image
(EN)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.
(FR)La présente invention concerne un phyllosilicate présentant une structure en couches sous la forme de plaquettes et comprenant un agent d'intercalation entre les plaquettes, l'agent d'intercalation étant un polyester ayant un poids moléculaire de 274 à 30 000 g/mol, et le phyllosilicate étant différent d'un phyllosilicate modifié par échange ionique. La présente invention concerne également un nanocomposite polymère comprenant un polymère de polyéthylène téréphtalate (PET) et le phyllosilicate mentionné ci-dessus, ainsi que des procédés de préparation pour la préparation du phyllosilicate intercalé et du nanocomposite de PET. Le nanocomposite de PET est particulièrement utile pour l'emballage, en particulier pour l'emballage d'aliments et de boissons.
