Embodiment 1
[0168] Nitrogen is replaced in a flask equipped with a temperature regulator, a stirring device, a condenser, a dropping funnel, and a nitrogen blowing port, and 34.9 g (0.3 mol) of indene, 200 g of toluene, and 8.72 g (0.027 mol) of tetranormal Butylammonium bromide, 1.79 g (0.009 mol) of phenothiazine, and 144.0 g (NaOH, 1.8 mol) of 50% by weight NaOH aqueous solution were heated to 50° C. while stirring to make a homogeneous solution. 150.8 g (purity 91%, 0.9 mol) of vinylbenzyl chloride CMS-AM (m / p isomer: 50 / 50% by weight mixture) manufactured by せイミケミカル Co. React at 50°C to 52°C for 10 hours. Then neutralize the contents of the flask with 2N hydrochloric acid, then wash 2 times with distilled water, remove the toluene under reduced pressure, wash the orange-yellow viscous liquid obtained with methanol, and then vacuum-dry to obtain the curable vinylbenzyl compound of the present invention ( It is mainly composed of compounds corresponding to the compounds in which R1, R...
