US 7,605,205 B2 · Nanocomposite compositions and processes for making the same

Abstract

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.

Dependent claims

A process for preparing a nanocomposite composition, comprising:

a) contacting a multifunctional intercalant comprising a cationic moiety separated from an anionic moiety by at least 1 carbon atom and an intercalation modifier with a clay at a temperature and for a period of time sufficient to produce an at least partially intercalated clay;
b) dissolving at least a portion of a functionalized interpolymer in a solvent to produce a functionalized interpolymer mixture wherein the functionalized interpolymer comprises C4 to C7 isoolefin derived units, multiolefin derived units and halogenated multiolefin derived units;
and
c) contacting the at least partially intercalated clay with the functionalized interpolymer mixture at a temperature, and for a period of time sufficient to produce the nanocomposite composition.
