This document describes a procedure for the determination of the following antidegradants in vulcanized rubbers:<\/p>\n

    \n
  1. \n

    aminoketone group;<\/p>\n<\/li>\n

  2. \n

    naphthylamine group;<\/p>\n<\/li>\n

  3. \n

    diphenylamine group;<\/p>\n<\/li>\n

  4. \n

    p-phenylenediamine;<\/p>\n<\/li>\n

  5. \n

    monophenol group.<\/p>\n<\/li>\n<\/ol>\n

    The groups of antidegradants are summarized in Table A.1<\/span> with the chemical names, the abbreviated terms and the CAS registry numbers.<\/p>\n

    Extender oils, when present, can interfere.<\/p>\n

    For poly-2,2,4-trimethyl-1,2-dihydroquinoline, the method provides only an approximation because of its polymeric nature.<\/p>\n
