Problems solved by technology

[0014] However, these polymerizable compounds only have two polymerizable groups at the end and one polymerizable group in the chain, and still do not have enough cross-linking points
[0015] The object of the present invention is to provide novel fumaric acid ester derivatives, which can overcome the problems in conventional radically polymerizable compounds, such as curing inhibition by oxygen or low surface hardness of cured products during curing, and which have sufficient multiple cross-links

Embodiment 1

[0240] In a 1-liter volumetric flask equipped with a distillation device, 312 grams of bis(2-allyloxyethyl) maleate, 135 grams of ethylene oxide 2-mole adduct of bisphenol A, 0.4 gram of dibutyltin oxide, and 0.12 gram of tetrakis[methylene-3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] methane (trade name "IRGANOX 1010", manufactured by Chiba Specialty Chemicals). While gradually reducing the pressure in the reaction system, the mixture was heated at 160° C., and ethylene glycol monoallyl ether produced as a by-product was distilled off. Finally, the pressure was reduced to about 400 Pa and almost the theoretical amount of ethylene glycol monoallyl ether was distilled off.

[0241] After cooling the reaction solution to room temperature, 385 g of product were obtained. measure the product 1 H-NMR ( 1 H-NMR) and IR (infrared spectroscopy), it was determined that this product was the condensation product of bis(2-allyloxyethyl) maleate and the ethylene oxide 2-mole adduc...

Embodiment 3

[0268] In the glass flask that stirring device, thermometer, condenser and the distillation acceptor with piston are equipped with in 500 milliliters of volumes, the single-2-allyloxyethyl fumarate of 154 grams embodiment 2 is charged into, 21.8 gram of pentaerythritol, 200 milliliters of benzene and 0.25 grams of p-toluenesulfonic acid. The mixture was heated with stirring in an oil bath, the reaction temperature was raised to 80°C, and water produced as a by-product as the reaction proceeded was distilled off while the reaction was continued. When the distilled-off amount of water reached the theoretical value, the reaction was terminated, and the reaction liquid was cooled. Transfer the reaction solution to a separatory funnel, add 300 ml of benzene, and separate with 10% aqueous sodium carbonate solution and water. Thereafter, the resulting solution was concentrated under reduced pressure to obtain 120 g of product.

Embodiment 4

[0273] In the glass flask that stirring device, thermometer, condenser and the distillation acceptor with piston are equipped with in 500 milliliters of volumes, the mono-2-allyloxyethyl fumarate of 152 grams embodiment 2 is charged into, 21.5 gram of trimethylolpropane, 200 ml of benzene and 0.25 gram of p-toluenesulfonic acid. The mixture was heated with stirring in an oil bath, the reaction temperature was raised to 80°C, and water produced as a by-product as the reaction proceeded was distilled off while the reaction was continued. When the distilled-off amount of water reached the theoretical value, the reaction was terminated, and the reaction liquid was cooled. Transfer the reaction solution to a separatory funnel, add 300 ml of benzene, and separate with 10% aqueous sodium carbonate solution and water. Thereafter, the resulting solution was concentrated under reduced pressure to obtain 118 g of product.
