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 flex ing fatigue, composed of a polyamide resin (A) , as a matrix, and a modifyin g polymer (C) ,~ dispersed therein, having a functional group (B) reactive w ith the polyamide resin (A) , wherein a tensile stress at break of the modif ying polymer (C) is 30 to 70% of the tensile stress at break of the polyamid e 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.
