    • An object of the present invention is, in a thermoplastic elastomer composition in which a modified rubber is filled and dispersed in a polyamide resin matrix in order to improve the low-temperature durability of the polyamide resin, to reduce the extrusion load during extrusion molding thereof into a film without deteriorating the low-temperature durability. The present invention is a thermoplastic elastomer composition (E) comprising a modified polyamide resin (C) and a modified rubber (D) dispersed in the modified polyamide resin (C), the modified polyamide resin (C) being a resin obtained by melt-blending an polyamide resin (A) and a compound (B) capable of reacting with a terminal amino group of a polyamide resin, wherein the modified rubber (D) has an acid anhydride group or epoxy group and is dynamically cross-linked by a compound (F) having at least one disulfide bond and at least two amino groups. This thermoplastic elastomer composition can be suitably used in the production of an inner liner of a pneumatic tire.
    • 本发明的目的在于,为了提高聚酰胺树脂的低温耐久性而将改性橡胶填充分散在聚酰胺树脂基体中的热塑性弹性体组合物中,为了降低挤出成型时的挤出负荷 成膜而不劣化低温耐久性。 本发明是一种热塑性弹性体组合物(E),其包含改性聚酰胺树脂(C)和分散在改性聚酰胺树脂(C)中的改性橡胶(D)),改性聚酰胺树脂(C) 混合聚酰胺树脂(A)和能够与聚酰胺树脂的末端氨基反应的化合物(B),其中改性橡胶(D)具有酸酐基或环氧基并通过化合物动态交联 (F)具有至少一个二硫键和至少两个氨基。 该热塑性弹性体组合物可以适用于充气轮胎的内衬的制造。
