PROBLEM TO BE SOLVED: To increase the production of a tricyclic aromatic hydrocarbon while maintaining or reducing the production of a bicyclic aromatic hydrocarbon and suppressing the production of unsaturated styrene compound oligomers. SOLUTION: A method for producing a monocyclic aromatic hydrocarbon-styrene compound adduct is provided, comprising the step(1) of carrying out a reaction between a monocyclic aromatic hydrocarbon and a styrene compound in a liquid phase in the presence of a solid catalyst in a fixed bed circulation-type reactor, the step(2) of circulating part of the resultant reaction product, the step(3) of obtaining respectively a bicyclic aromatic hydrocarbon and a tricyclic aromatic hydrocarbon as monocyclic aromatic hydrocarbon-styrene compound adducts and the step(4) of circulating part of the resultant bicyclic aromatic hydrocarbon to the reactor, thus adding the styrene compound to the monocyclic aromatic hydrocarbon having at least one hydrogen atom directly bound to an aromatic ring hydrocarbon atom.

PURPOSE: To obtain the subject compound, excellent in weather and heat resistances, etc., and capable of providing an unsaturated α-olefin-polyene copolymer having a high vulcanization rate by reacting a vinylnorbornene compound with a conjugated diene compound in the presence of a catalyst. CONSTITUTION: A vinylnorbornene compound of formula I (R and R are each H or a 1-5C alkyl) (preferably 5-vinylnorbornene, etc.) is reacted with a conjugated diene compound of formula II (R and R are each H or a 1-5C alkyl; R is H or a 1-4C alkyl, with the proviso that R and R are not simultaneously H) (e.g. isoprene) in the presence of a catalyst to afford the objective compound of formula III. Furthermore, a catalyst comprising a transition metallic complex in which an organic ligand is coordinated with Co chloride and triethylaluminum is preferred as the catalyst. 9146/28}1,2-Bis(diphenylphosphino)ethane]cobalt (II) chloride, etc., are preferred as the transition metallic complex. The reaction is preferably carried out at 70-150 deg.C under 10-70kg/cm ethylene pressure.
