Abstract:
(EN) The purpose of the present invention is to provide: a rubber composition which retains extremely low heat build-up properties and a high elongation at rupture and has an excellent modulus at 100% elongation; a process for producing the rubber composition; and a pneumatic tire. The rubber composition of the present invention comprises a diene-based rubber, a filler, and at least one acid-modified polyolefin-based polymer selected from the group consisting of acid-modified polyethylenes and acid-modified polypropylene-based polymers, the acid-modified polyethylenes each having a density of 0.94-0.98 g/cm3 and the acid-modified polypropylene-based polymers each having a melting point of 136-155ºC, wherein the content of the acid-modified polyolefin-based polymer is 1-30 parts by mass per 100 parts by mass of the diene-based rubber.
(FR) La présente invention concerne : une composition de caoutchouc qui conserve des propriétés extrêmement faibles d’accumulation de chaleur et un fort allongement à la rupture et présente un excellent module à 100 % d’allongement ; un procédé de production de la composition de caoutchouc ; et un bandage pneumatique. La composition de caoutchouc de la présente invention comprend un caoutchouc à base de diène, une charge, et au moins un polymère à base de polyoléfine modifié avec un acide sélectionné dans le groupe constitué des polyéthylènes modifiés avec un acide et des polymères à base de polypropylène modifiés avec un acide, les polyéthylènes modifiés avec un acide ayant chacun une densité de 0,94 à 0,98 g/cm3 et les polymères à base de polypropylène modifiés avec un acide ayant chacun un point de fusion de 136 à 155 ºC, où la teneur du polymère à base de polyoléfine modifié avec un acide est de 1 à 30 parties en masse pour 100 parties en masse du caoutchouc à base de diène.
(JA) 本発明は、高い低発熱性、破断伸びを維持しつつ、100%伸長時のモジュラスに優れるゴム組成物、その製造方法及び空気入りタイヤの提供を目的とする。本発明は、ジエン系ゴムと、充填剤と、酸変性ポリエチレン及び酸変性ポリプロピレン系重合体からなる群から選ばれる少なくとも1種の酸変性ポリオレフィン系重合体と、を含有し、上記酸変性ポリエチレンの密度が0.94~0.98g/cm3であり、上記酸変性ポリプロピレン系重合体の融点が136~155℃であり、上記酸変性ポリオレフィン系重合体の含有量が上記ジエン系ゴム100質量部に対して1~30質量部である、ゴム組成物である。
