    • A durable, flexible, impermeable thermoplastic elastomer composition is produced using a dynamic vulcanization process conducted in a high shear mixer at elevated temperature. The composition comprises cured particles of a first halogenated isobutylene-containing elastomer and particles of a second elastomer having at least one functional group capable of reacting with and grafting to a polyamide, the particles of the first and second elastomers dispersed in a continuous thermoplastic polyamide matrix, said process comprising: (1) dispersing a curative in the halogenated elastomer and forming a pre-compounded, preferably pelletized composition; (2) introducing polyamide resin and optional stabilizers into the mixer and shearing and heating to melt the polyamide and form a mixture; (3) introducing a nylon plasticizer to reduce the viscosity of the polyamide mixture to substantially match that of the pre-compounded elastomer under mixing conditions; (4) introducing pellets of the pre-compounded elastomer into the mixer and initiating dynamic vulcanization of the elastomer and polyamide components; (5) introducing the second elastomer and continuing heating and shearing to disperse the second elastomer and substantially complete dynamic vulcanization; and delivering the thermoplastic elastomer composition from the mixer. Such compositions are particularly useful in applications such as tire innerliners and barrier films or layers.
    • 使用在高剪切混合器中在高温下进行的动态硫化方法制备耐用的,柔性的,不渗透的热塑性弹性体组合物。 该组合物包含含有第一卤代异丁烯的弹性体的固化颗粒和具有至少一个能够与聚酰胺反应和接枝到聚酰胺上的官能团的第二弹性体颗粒,第一和第二弹性体的颗粒分散在连续的热塑性聚酰胺基质 所述方法包括:(1)将固化剂分散在卤化弹性体中并形成预混合的,优选颗粒状的组合物; (2)将聚酰胺树脂和任选的稳定剂引入混合器中并剪切和加热以熔化聚酰胺并形成混合物; (3)在混合条件下引入尼龙增塑剂以降低聚酰胺混合物的粘度与预混合弹性体的粘度基本一致; (4)将预混合弹性体的颗粒引入混合器中并引发弹性体和聚酰胺组分的动态硫化; (5)引入第二弹性体并继续加热和剪切以分散第二弹性体并基本上完成动态硫化; 并从混合器输送热塑性弹性体组合物。 这样的组合物特别适用于诸如轮胎内衬和阻挡膜或层的应用。
