Title (EN) RUBBER COMPOSITION AND PNEUMATIC TIRE
(FR) COMPOSITION DE CAOUTCHOUC ET PNEU
(JA) ゴム組成物および空気入りタイヤ
Abstract:
(EN) The objective of the present invention is to provide: a rubber composition which enables the production of a pneumatic tire having excellent wet skid performance, while maintaining good heat generation reducing effect; and a pneumatic tire which uses this rubber composition. A rubber composition according to the present invention contains a white filler and a diene rubber that contains 5-40% by mass of a modified butadiene rubber. The modified butadiene rubber is a modified polymer that is obtained by modifying (A) an unmodified butadiene rubber with (B) a nitrone compound having a carboxy group.
(FR) La présente invention concerne : une composition de caoutchouc qui permet la production d'un pneu ayant d'excellentes performances d'aquaplanage, tout en maintenant un effet de réduction de génération de chaleur satisfaisant; et un pneu qui utilise cette composition de caoutchouc. Une composition de caoutchouc selon la présente invention contient une charge blanche et un caoutchouc diène qui contient 5 à 40 % en masse d'un caoutchouc butadiène modifié. Le caoutchouc butadiène modifié est un polymère modifié qui est obtenu par modification de (A) un caoutchouc butadiène modifié avec (B) un composé de nitrone ayant un groupe carboxy.
(JA)  本発明の課題は、良好な発熱性の低減効果を維持しつつ、ウェットスキッド性能に優れた空気入りタイヤを作製することができるゴム組成物およびそれを用いた空気入りタイヤを提供することである。本発明のゴム組成物は、変性ブタジエンゴムを5~40質量%含むジエン系ゴムと、白色充填剤とを含有し、前記変性ブタジエンゴムが、未変性ブタジエンゴム(A)を、カルボキシ基を有するニトロン化合物(B)によって変性することで得られる変性ポリマーである、ゴム組成物である。
