Embodiment 1
[0054] (1) A kind of synthetic method of described nitrile-based resin monomer
[0055] Step 1: Add diallyl bisphenol A, anhydrous potassium carbonate and dimethyl sulfoxide into a dry reaction vessel, heat in a water bath to 60° C., and reflux for 5 hours.
[0056] Step 2: Add 4-nitrophthalonitrile into the reaction vessel described in Step 1, and react under reflux at 60° C. for 3 hours.
[0057] Step 3: Filter the reaction mixture obtained in step 2 under anhydrous conditions.
[0058] Step 4: Pour the filtrate obtained in step 3 into clear water to precipitate and filter, and the solid obtained by filtering is washed with a large amount of clear water and then fully dried to obtain the final product nitrile resin monomer.
[0059] Wherein, the molar volume ratio of diallyl bisphenol A, anhydrous potassium carbonate, dimethyl sulfoxide and 4-nitrophthalonitrile is as follows:
[0060] Diallyl bisphenol A (grams)
137
Anhydrous Potassium Carbonate (g)
