고강도이며, 또한 저연비 성능이 우수한 가교 고무를 얻을 수 있고, 가공성이 우수한 고무 조성물을 얻을 수 있는 수소 첨가 공액 디엔계 고무를 제공한다. 부타디엔 단위의 수소 첨가율이 90% 이상인 수소 첨가 공액 디엔계 고무이며, 상기 수소 첨가 공액 디엔계 고무의 겔 투과 크로마토그래피법에 의해 구해지는 분자량 분포에 있어서, 분자량 1,000 내지 250,000의 피크 면적을 AL, 분자량 250,000 이상의 피크 면적을 AH로 했을 때에, AL과 AH의 합계 면적에 대한 AL의 비율이 0.5% 이상 20% 이하인 수소 첨가 공액 디엔계 고무.
There is provided a hydrogenated conjugated diene-based rubber which can give a crosslinked rubber having high strength and excellent low fuel consumption performance and can give a rubber composition having excellent formability. A hydrogenated conjugated diene-based rubber having a hydrogenation rate of butadiene unit of 90% or more, wherein, in the molecular weight distribution of the hydrogenated conjugated diene-based rubber as determined by a gel permeation chromatographic method, when a peak area of a molecular weight of 1,000 to 250,000 is taken as AL and a peak area of a molecular weight of 250,000 or more is taken as AH, the ratio of AL to the total area of AL and AH is 0.5% to 20%.
