POLYMER ALLOY, RUBBER PRODUCT, AND METHOD FOR PRODUCING POLYMER ALLOY AND RUBBER PRODUCT

摘要

[Problem] To provide a polymer alloy and rubber product composed of a non-polar rubber and a polar rubber, in which ozone resistance (weather resistance) can be improved and high mechanical strength (in particular, tensile strength) can be achieved while oil resistance is also provided, and to provide a method for producing a polymer alloy and rubber product. [Solution] A rubber product in which an organic peroxide or other cross-linking agent is used to cross-link a polymer alloy comprising: a modified rubber in which EPDM, NR, or another non-polar rubber having a non-conjugated double bond is modified with 2-methoxy-1-naphthonitrile oxide, 2,6-dimethoxy benzonitrile oxide, or another nitrile oxide of an aromatic nitrile oxide derivative; and nitrile rubber, acrylic rubber, or another polar rubber.
