Abstract
(EN)
Disclosed is a rubber composition having a high storage modulus (G’) and a low loss tangent (tan &dgr;). Specifically disclosed is a rubber composition characterized by containing 2-60 parts by mass of a low molecular-weight aromatic vinyl compound-conjugated diene compound copolymer (B) having at least one functional group per 100 parts by mass of a rubber component (A). The rubber component (A) is composed of at least one rubber selected from natural rubbers and synthetic diene rubbers. The low molecular-weight aromatic vinyl compound-conjugated diene compound (B) is characterized in that the aromatic vinyl compound content is 5-80% by mass, the vinyl bond content in the conjugated diene compound unit is 5-80% by mass, and the weight average molecular weight in terms of polystyrene as determined by gel permeation chromatography is 5,000-500,000.

Il est exposé une composition de caoutchouc ayant un module de conservation (G') élevé et une faible tangente de perte (tan &dgr;). Il est précisément exposé une composition de caoutchouc caractérisée en ce qu'elle contient 2-60 parties en poids d'un copolymère de faible poids moléculaire d'un composé vinylique aromatique et d'un composé diénique conjugué (B) ayant au moins un groupe fonctionnel pour 100 parties en poids d'un composant caoutchouc (A). Le composant caoutchouc (A) est composé d'au moins un caoutchouc sélectionné parmi des caoutchoucs naturels et des caoutchoucs diéniques synthétiques. Le copolymère de faible poids moléculaire d'un composé vinylique aromatique et d'un composé diénique conjugué (B) est caractérisé en ce que la teneur en composé vinylique aromatique est de 5-80 % en poids, la teneur des liaisons vinyliques dans l'unité constituée du composé diénique conjugué est de 5-80 % en poids et le poids moléculaire moyen en poids en équivalent du polystyrène tel que déterminé par chromatographie de perméation de gel est de 5 000-500 000.
