[0262] Synthesis Example 1 (Synthesis of Acryloyl Acrylate A1)
[0263] In a reaction device equipped with a stirring device, a condenser, a dropping funnel, and a nitrogen gas introduction pipe, 500 parts by mass of methyl isobutyl ketone was charged, and the temperature in the system was raised to 110° C. while stirring, and then, it was used for 2 hours from The dropping funnel was dripped with 250 parts by mass of glycidyl methacrylate, 80 parts by mass of methyl methacrylate, 40 parts by mass of ethyl acrylate and tert-butyl peroxy-2-ethylhexanoate (Nippon Emulsifier Co., Ltd. "Perbutyl O") 5.5 parts by mass of the mixed solution, and then kept at 110°C for 15 hours. Next, the temperature was lowered to 90°C, and after loading 5 parts by mass of p-methoxyphenol and 130 parts by mass of acrylic acid, 2.6 parts by mass of triphenylphosphine was added, and the temperature was further raised to 100°C and kept for 8 hours to obtain acrylic acid acryloyl 997 parts by mass of m...
