The present invention relates to a hydrogenated petroleum resin and a rubber composition comprising the same, wherein the hydrogenated petroleum resin, according to the present invention, not only improves viscoelastic properties of the rubber containing the same, but also can improve the overall physical properties of the rubber with excellent compatibility with the rubber. Accordingly, rubber molded articles prepared from the rubber composition comprising the hydrogenated petroleum resin, for example, tires have improved gripping power (wet/dry) and lower an increase in rotational resistance due to the improved gripping power to simultaneously satisfy two physical properties of gripping power and rolling resistance required as a tire, thereby being able to prepare a low-fuel-efficient and high-performance tire.
본 발명은 수소첨가 석유수지 및 이를 포함하는 고무 조성물에 관한 것으로, 본 발명에 따른 수소첨가 석유수지는 이를 포함하는 고무의 점탄성 특성을 향상시킬 뿐만 아니라 고무와의 상용성이 우수하여 고무의 전반적인 물성을 개선시킬 수 있다. 이에 상기 수소첨가 석유수지를 포함하는 고무 조성물로부터 제조된 고무 성형품, 예컨대 타이어는 그립력(wet/dry)이 향상되고, 그립력 향상에 따른 회전 저항의 상승폭을 낮춰 타이어로서 요구되는 그립력과 회전 저항의 두 가지 물성을 동시에 만족시킴으로써 저연비 고성능 타이어를 제조할 수 있다.
