PURPOSE: To prevent formation of by-products of polymer, by carrying out Diels-Alder reaction of a conjugated diolefin compound and an olefin compound in the presence of an alkylphenolic compound. n CONSTITUTION: Diels-Alder reaction of a conjugated olefin compound and an olefin compound is carried out in the presence of 10W10,000ppm (preferably 100W5,000ppm) based on the total amounts of a compound shown by the formula (R 1 WR 3 are H, or 1W6C alkyl). 2,6-Di-6-butylphenol, 2,6-xylenol, etc. may be cited as the compound shown by the formula. n EFFECT: A polymerization reaction can be suppressed, and continuous operation can be carried out for a long time without hindrance. n COPYRIGHT: (C)1986,JPO&Japio |
