The invention provides for curable compositions containing a halogenated copolymer of a C4 to C7 isomonoolefin, e.g., isobutylene and a para- alkylstyrene, e.g., para-methylstyrene, and further containing an effective amount of a metal salt, e.g., zinc, of an unsaturated carboxylic acid, e.g., methacrylic acid, as a curing agent. The composition also contains an organic peroxide as a co-curative and one or a mixture of saturated or olefinically unsaturated polymer blend components which are co-curable with the halogenated copolymer.
L'invention concerne des compositions susceptibles de subir une cuisson contenant un copolymère halogéné d'un isomonooléfine C¿4? à C¿7?, par exemple de l'isobutylène, et un para-alkylstyrène, par exemple du para-méthylstyrène, ainsi qu'une quantité efficace d'un sel métallique, par exemple du zinc, et d'un acide carbolyxique non saturé, par exemple de l'acide méthacrylique, comme agent de cuisson. La composition contient également un peroxyde organique comme co-agent de cuisson et un seul ou un mélange de composants d'un mélange de polymères saturés ou alcéniques susceptibles de subir une cuisson avec le copolymère halogéné.
