    摘要: A nitrile copolymer rubber composition containing a nitrile copolymer rubber (A) which contains ±,²-ethylenically unsaturated nitrile monomer units (a1) 35 to 85 wt%, conjugated diene monomer units which may be at least partially hydrogenated (a2) 15 to 65 wt%, cationic monomer units (a3) 0 to 30 wt%, and aromatic vinyl monomer units (a4) 0 to 50 wt%, the total content of the ±,²-ethylenically unsaturated nitrile monomer units (a1) and the aromatic vinyl monomer units (a4) being 35 to 85 wt%, a vinyl chloride resin (B), and a plasticizer (C) with a specific structure is provided.

    摘要: A highly saturated nitrile copolymer rubber which comprises 10 to 40 wt.% alpha , beta - ethylenically unsaturated nitrile monomer units (a), 10 to 60 wt.% alpha , beta - ethylenically unsaturated carboxylic ester monomer units (b), 0.01 to 56 wt.% conjugated diene monomer units (c), and 35 to 69.95 wt.% saturated conjugated diene monomer units (d), in which the total content of the monomer units (c) and the monomer units (d) is 20 to 70 wt.%, the monomer units (d) account for 70 wt.% or more of the sum of the monomer units (c) and the monomer units (d), and the difference between the extrapolated glass transition initiation temperature (Tig) and the extrapolated glass transition ending temperature (Teg) in differential scanning calorimetry is 10 DEG C or lower. The rubber is compounded with a crosslinking agent to crosslink it. Thus, a crosslinked object excellent in cold resistance, oil resistance, and dynamic properties is obtained.
