摘要： A nitrile group-containing copolymer rubber containing ±,²-ethylenically unsaturated nitrile monomer units in a ratio of 10 to 60 wt% and having a Z-average radius of gyration of 100 nm or more is provided. Preferably, the nitrile group-containing copolymer rubber of the present invention has an iodine value of 120 or less. Further, preferably, the nitrile group-containing copolymer rubber of the present invention has a plasticity number of 14 to 90. According to the present invention, it is possible to provide a nitrile group-containing copolymer rubber able to give a cross-linked rubber excellent in tensile stress, compression set resistance, and low heat buildup property.

摘要： The present invention aims to provide a laminate including a fluororubber layer and an acrylic rubber layer which are firmly bonded to each other and are not separated even at high temperatures. The laminate of the present invention includes a fluororubber layer and an acrylic rubber layer. The fluororubber layer is formed from a fluororubber composition containing a fluororubber that contains a polyol-crosslinkable vinylidene fluoride unit, a polyol crosslinker, and a crosslinking accelerator. The crosslinking accelerator is a quaternary phosphonium salt free from a chlorine atom. The fluororubber has an acid value of 0.20 KOHmg/g or higher.
