CA 2628710

The invention provides for processes for preparing a nanocomposite compositions including the steps of: contacting a multifunctional intercalant including a cationic moiety separated from an anionic moiety by at least 1 carbon, with a clay at a temperature and for a period of time sufficient to produce an at least partially intercalated clay; and contacting the at least partially intercalated clay with a functionalized interpolymer including one or more functional groups, at a temperature, and for a period of time sufficient to produce the nanocomposite compositions. Cured nanocomposite compositions, and articles including such nanocomposite compositions are also provided.

L~invention concerne des procédés de fabrication de compositions nanocomposites, lesdits procédés comprenant les étapes suivantes : mettre en contact un intercalant multifonctionnel, comprenant une fonction cationique séparée d~une fonction anionique par au moins 1 carbone, avec une argile à une température suffisante et pendant une durée suffisante pour obtenir une argile au moins en partie intercalée ; et mettre en contact ladite argile au moins en partie intercalée avec un interpolymère fonctionnalisé comprenant un ou plusieurs groupes fonctionnels, à une température suffisante et pendant une durée suffisante pour obtenir les compositions nanocomposites. L~invention concerne également des compositions nanocomposites durcies et des articles comprenant de telles compositions nanocomposites.
