Embodiment 1
[0144] In 10 parts of isostearyl methacrylate ("NK ester S-1800M" manufactured by Shin Nakamura Chemical Industry Co., Ltd.), 10 parts of methyl methacrylate and bis (oxymethyl) tricyclo [5, 2, 1 ,0 2,6 ] In 100 parts of a mixture of 80 parts of decane dimethacrylate, 0.05 parts of 2,2'-azobis(2,4-dimethyl-4-methoxyvaleronitrile) as a polymerization initiator were mixed, 0.05 part of tert-butyl peroxy pivalate, 0.05 part of tert-hexyl peroxy isopropyl carbonate and 0.03 part of terpinolene as a polymerization regulator, and the resulting mixture is put into a suction filter bottle, stirred, and vacuum removed gas to obtain a polymerization mixture.
[0145] The polymerization mixture was poured into a mold formed by inserting a gasket between a pair of tempered glass sheets at a distance of 1.7mm, and air bubbles were removed, and then placed in a heating furnace, and polymerized at 55°C for 1 hour, then at 50°C for 1 hour, and then heated at 135°C Polymerized for 3 hours. ...
Embodiment 2~24
[0147] [Examples 2-24, Comparative Examples 1-9]
[0148] Except having used the raw material composition shown in Tables 1-6, it carried out similarly to Example 1, and produced the acrylic resin board. The evaluation results are shown in Tables 1-6.
Embodiment 25
[0150] In Example 1, 0.05 part of n-dodecyl mercaptan was further added as a chain transfer agent to the polymerization mixture, and the rest was carried out in the same manner as in Example 1 to produce an acrylic resin plate. The evaluation results are shown in Table 7. Moreover, bis(oxymethyl)tricyclo[5,2,1,0 2,6 ] The residual monomer amount of decane dimethacrylate was 2.09%.
