preparation example 1
[0107]
[0108] 350g (0.5mol) of OL-1001 (purchased from FRX company in the United States, n is 3) and 1000g of appropriate amount of toluene were placed in a three-necked flask, to which was added 28.5g (0.5mol) of allylamine, 75g (1mol) of Aqueous methanol (40%). After the addition, the temperature was raised to 90°C at a heating rate lower than 2°C / min, and the reaction was carried out for 5h. Then the temperature was raised to 120°C, and the solvent was drained within 60 minutes under a pressure of less than 30tor, and the resin was transferred to a beaker, and cooled in ice water to obtain a phosphorus-containing unsaturated bond benzoxazine resin.

[0112] 400g (0.25mol) of terminal hydroxy phosphate (purchased from ICL, n is 6) and 1000g appropriate amount of toluene were placed in a three-necked flask, 14.25g (0.25mol) of allylamine was added to it, 75g (0.5mol) of Aqueous methanol (40%). After the addition, the temperature was raised to 90°C at a heating rate lower than 2°C / min, and the reaction was carried out for 5h. Then the temperature was raised to 120°C, and the solvent was drained within 60 minutes under a pressure of less than 30tor, and the resin was transferred to a beaker, and cooled in ice water to obtain a phosphorus-containing unsaturated bond benzoxazine resin.

[0116] 370g (0.5mol) of SPH-100 (purchased from Japan Otsuka Chemical) and 1000g appropriate amount of toluene were placed in a three-necked flask, 28.5g (0.5mol) of allylamine, 75g (1.0mol) of methanol aqueous solution ( 40%). After the addition, the temperature was raised to 90°C at a heating rate lower than 2°C / min, and the reaction was carried out for 5h. Then the temperature was raised to 120°C, and the solvent was drained within 60 minutes under a pressure of less than 30tor, and the resin was transferred to a beaker, and cooled in ice water to obtain a phosphorus-containing unsaturated bond benzoxazine resin.
