    摘要： An embodiment of the present invention is a nanocomposite comprising a clay and an elastomer comprising at least C2 to C10 olefin derived units; wherein the elastomer also comprises functionalized monomer units pendant to the elastomer. Desirable embodiments of the elastomer include poly(isobutylene-co-p-alkylstyrene) elastomers and poly(isobutylene-co-isoprene) elastomers, which are functionalized by reacting free radical generating agents and unsaturated carboxylic acids, unsaturated esters, unsaturated imides, and the like, with the elastomer. The clay is exfoliated in one embodiment by the addition of exfoliating agents such as alkyl amines and silanes to the clay. The composition can include secondary rubbers such as general purpose rubbers, and curatives, fillers, and the like. The nanocomposites of the invention have improved air barrier properties such as are useful for tire innerliners and innertubes.

    摘要： The present invention is a blend of an halogenated elastomer and a clay, desirably an exfoliated clay, to form a nanocomposite suitable for an air barrier. In one embodiment, the halogenated elastomer is a polymer comprising C4 to C7 isoolefin derived units, a para-methylstyrene derived units, and para-(halomethylstyrene) derived units. In another embodiment, the halogenated elastomer is a butyl-type rubber. The clay may or may not have an additional exfoliating treatment present prior to blending with the interpolymer. The interpolymer/clay mixture forms a distinct phase in the nanocomposite blend of the invention. The blend of the invention has improved air barrier properties and is suitable as an innerliner or innertube.

    摘要： The present invention is a process to produce a nanocomposite of a elastomer and organic clay, e.g. an exfoliated clay, suitable for use as an air barrier. The process can include the steps of: (a) contacting a solution (10) of butyl rubber in an organic solvent with a halogen (12) to form a halogenated butyl rubber solution (16); (b) neutralizing the halogenated butyl rubber solution; (c) functionalizing at least a portion (18) of the halogenated butyl rubber; (d) mixing a dispersion (22) of clay with the functionalized butyl rubber (18) to form a masterbatch (26) comprising a polymer-clay nanocomposite; (e) combining the masterbatch (26) with the rest of the halogenated butyl rubber solution (20) to form a second mixture (28); (e) recovering the nanocomposite from the second mixture (28). The nanocomposite so formed has improved air barrier properties and is suitable for use as a tire innerliner or innertube.
