摘要： Proposed is a rubber process oil including a base oil, a liquid olefin copolymer prepared by copolymerization of ethylene with an alpha-olefin having 3 to 20 carbon atoms, polyisobutylene, and one or more additives selected from among alkylated phosphonium phosphate compounds and butylhydroxybenzene-based compounds. A rubber composition including the rubber process oil is also proposed.
