Polyamide resin composition having superior extensibility and flexing fatigue and pneumatic tire and hose using the same
摘要：
A polyamide resin composition, having an excellent extensibility and flexing fatigue, composed of a polyamide resin (A), as a matrix, and a modifying polymer (C), dispersed therein, having a functional group (B) reactive with the polyamide resin (A), wherein a tensile stress at break of the modifying polymer (C) is 30 to 70% of the tensile stress at break of the polyamide resin (A), and a tensile elongation at break of the modifying polymer (C) is 100 to 500% of the tensile elongation at break of the polyamide resin (A) as well as a pneumatic tire and hose using the same.
摘要（中）：

具有聚酰胺树脂（A），作为基质的聚酰胺树脂（A）和分散有聚酰胺树脂（B）的官能团（B））的改性聚合物（C）具有优异的伸长性和挠曲疲劳性的聚酰胺树脂组合物 A），其中，改性聚合物（C）的断裂拉伸应力为聚酰胺树脂（A）的断裂拉伸应力的30〜70％，改性聚合物（C）的拉伸断裂伸长率为100 至聚酰胺树脂（A）的断裂拉伸伸长率的500％，以及使用其的充气轮胎和软管。
