    • Pneumatic tyre with built-in self-sealing layer comprising an outer rubbery tread, a carcass reinforcement, a gastight layer positioned on the inside relative to the carcass reinforcement, a protective layer positioned innermost and a self-sealing layer adjacent to the protective layer and positioned on the inside relative to the gastight layer, characterized in that said protective layer is a thermoplastic film comprising a copolymer containing hard blocks and soft blocks corresponding to the formula: -(BR-BS)n- where: BR represents a hard block composed of a polyamide or of a blend of polyamides; BS represents a soft block composed of a polyether, a blend of polyethers or a polyether/polyester copolymer; and n represents the number of (BR-BS) units of said block copolymer; such as, for example, a poly(ether-block-amide) copolymer.
    • 具有内置自密封层的气动轮胎,包括外橡胶状胎面,胎体增强件,相对于胎体增强件定位在内侧的气密层,位于最内侧的保护层和与保护层相邻的自密封层, 其特征在于,所述保护层是包含含有对应于下式的硬嵌段和软嵌段的共聚物的热塑性膜: - (BR-BS)n-其中:BR表示构成的硬嵌段 的聚酰胺或聚酰胺的共混物; BS表示由聚醚,聚醚或聚醚/聚酯共聚物的共混物组成的软嵌段; n表示所述嵌段共聚物的(BR-BS)单元数; 例如聚(醚 - 嵌段 - 酰胺)共聚物。

    • A pneumatic tire with a built-in self-sealing layer includes an outer rubbery tread, a carcass reinforcement, a gastight layer located at an inside position relative to the carcass reinforcement, a protective layer located at an innermost position, and a self-sealing layer adjacent to the protective layer and located at an inside position relative to the gastight layer. The protective layer is a thermoplastic film that includes a copolymer formed of at least hard blocks and soft blocks corresponding to a formula: -(BR-BS)n-, where: BR represents a hard block composed of a polyamide or of a blend of polyamides; BS represents a soft block composed of a polyether, a blend of polyethers, or a polyether/polyester copolymer; and n represents a number of (BR-BS) units of the block copolymer, such as, for example, a poly(ether-block-amide) copolymer.
