高饱和丁腈橡胶组合物和橡胶交联物
摘要：
本发明提供高饱和丁腈橡胶组合物，其包含含有羧基的高饱和丁腈橡胶（A1）、高饱和丁腈橡胶（A2）和聚酰胺树脂（B），所述含有羧基的高饱和丁腈橡胶（A1）含有α，β-烯键式不饱和腈单体单元15～60重量%和α，β-烯键式不饱和二羧酸单酯单体单元1～60重量%，碘值为120以下；所述高饱和丁腈橡胶（A2）含有α，β-烯键式不饱和腈单体单元15～60重量%，α，β-烯键式不饱和二羧酸单酯单体单元的含量为0.9重量%以下，碘值为120以下；所述含有羧基的高饱和丁腈橡胶（A1）和所述高饱和丁腈橡胶（A2）的含有比例以“含有羧基的高饱和丁腈橡胶（A1）：高饱和丁腈橡胶（A2）”的重量比计为2：98～98：2。
摘要（英）：

A highly saturated nitrile rubber composition containing a carboxyl group-containing highly saturated nitrile rubber (A1) which contains ±,²-ethylenically unsaturated nitrile monomer units 15 to 60 wt% and ±,²-ethylenically unsaturated dicarboxylic acid monoester monomer units 1 to 60 wt% and has an iodine value of 120 or less, a highly saturated nitrile rubber (A2) which contains ±,²-ethylenically unsaturated nitrile monomer units 15 to 60 wt%, has a content of the ±,²-ethylenically unsaturated dicarboxylic acid monoester monomer units of 0.9 wt% or less, and has an iodine value of 120 or less, and a polyamide resin (B), a content ratio of the carboxyl group-containing highly saturated nitrile rubber (A1) and the highly saturated nitrile rubber (A2) being a weight ratio of "carboxyl group-containing highly saturated nitrile rubber (A1): highly saturated nitrile rubber (A2)" of 2:98 to 98:2, is provided.
