    摘要: The invention relates to antioxidant compositions for lubricants and organic polymers comprising a first antioxidant comprising a reaction product of p-cresol, dicyclopentadiene and isobutylene; and a second antioxidant comprising a diarylamine. The first antioxidant preferably has the structure: wherein n is 0-50, and R 1 and R 2 are independently hydrogen, a straight or branched C 1 -C 30 alkyl or alkylene group optionally substituted with one or more substituents, C 3 -C 12 cycloalkyl, C 5 -C 12 aryl, or C 6 -C 12 alkylaryl. The second antioxidant preferably has the formula: (R 3 ) a -Ar 1 -NH-Ar 2 -(R 4 ) b wherein Ar 1 and Ar 2 are independently aromatic hydrocarbon groups and R 3 and R 4 are indenpendently hydrogen or hydrocarbyl groups having from 6 to about 100 carbon atoms and a and b are independently 0 to 3 but (a+b) is not greater than 4.
