9 Claims

1. A method for producing a hydrocarbon resin hydride, comprising:

hydrogenating a hydrocarbon resin by bringing the hydrocarbon resin into contact with hydrogen in the presence of an antioxidative compound and a hydrogenation catalyst, the antioxidative compound being at least one selected from the group consisting of hindered phenolic antioxidants and antioxidants having a 2,2,6,6-tetraalkyl-4-piperidyl group,

wherein the hydrocarbon resin is prepared by cationic polymerization of a monomer mixture containing an unsaturated hydrocarbon in the presence of a Lewis acid catalyst.
