Procedure

At 170° C., 156 g of propylene were reacted with 243 g of dimethyldicyclopentadiene for 20 hours, and by vacuum distillation 93 g of dimethylnorbornene were obtained. Then, 91 g of the thus prepared dimethylnorbornene were reacted with 135 g of dimethyldicyclopentadiene at 165° C. for 20 hours, and for the resultant reaction liquid, vacuum distillation was carried out to obtain 73 g of a 1:1 adduct of dimethylnorbornene and methylcyclopentadiene, i.e., a 2:1 adduct of methylcyclopentadiene and propylene at a boiling point of 97° C./2 mmHg.
