  • Polymer alloy and rubber product, and production method thereof
    Patent number: 8969480
    Abstract: To provide a polymer alloy formed of a non-polar rubber and a polar rubber, and a rubber product, which are improved in ozone resistance (weather resistance) while having oil resistance and can achieve high mechanical strength (in particular, tensile strength), and a production method thereof. 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-dimethoxybenzonitrile oxide, or another nitrile oxide of an aromatic nitrile oxide derivative; and nitrile rubber, acrylic rubber, or another polar rubber.

  • Crosslinkable polymer material, crosslinked polymer material, and production method thereof
    Patent number: 8507611
    Abstract: The present invention provides a production method of a crosslinkable polymer material which includes adding 2 -(glycidyloxy)-1-naphthonitrile oxide or 2-[5 -(ethoxycarbonyl)pentyloxy]-1-naphthonitrile oxide by an addition reaction to a polymer material having a multiple bond to which a nitrile oxide is added by an addition reaction so as to introduce a glycidyl group or an ethoxycarbonyl group into the polymer material.
