    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.

Desirable embodiments of the elastomer include poly(isobutylene-co-p-alkylstyrene) elastomers and poly(isobutylene-co-isoprene) elastomers, which are functionalized via Friedel-Crafts reaction with a Lewis acid and a functionalizing agent such as acid anhydrides and/or acylhalides. 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： A branched isobutylene-styrenic elastomer with a broad molecular weight distribution is disclosed comprising an interpolymer of an isoolefin monomer as isobutylene, a styrenic monomer such as p-methylstyrene, and a multiolefin such as divinylbenzene. The elastomer has improved green strength, relaxation characteristics, and processability in melt processing, while retaining excellent aging characteristics and barrier properties, and can be used in a blend with a linear isobutylene-p-alkylstyrene elastomer to improve processability of the linear elastomer. Also disclosed are a method for processing the linear elastomer with an effective amount of the branched elastomer to improve processability, and nanocomposites, curable compositions, cured compositions and useful articles formed from the branched elastomer and the linear-branched elastomer blends.
