Example Embodiment
[0106] (Example 1)
[0107] Mix 100 parts by weight of methyl methacrylate (MMA) and 100 parts by weight of terpineol as an organic solvent in a 2L separable flask equipped with a stirrer, a cooler, a thermometer, a hot water bath, and a nitrogen inlet to obtain a single Body mixture.
[0108] After bubbling the obtained monomer mixture with nitrogen for 20 minutes to remove dissolved oxygen, the inside of the separable flask was replaced with nitrogen, and while stirring, the oil tank was heated to 130°C. A solution obtained by diluting 2,2'-azobis[2-methyl-N-(2-hydroxyethyl)propionamide] with terpineol as a polymerization initiator was added. In addition, the terpineol solution containing the polymerization initiator was added several times during the polymerization, and a total of 1.5 parts by weight of the polymerization initiator was added with respect to 100 parts by weight of the monomer.
[0109] After 7 hours from the start of the polymerization, it was cooled to room temp...
Example Embodiment
[0112] (Example 2)
[0113] In a 2L separable flask equipped with a stirrer, a cooler, a thermometer, a hot water bath, and a nitrogen inlet, 100 parts by weight of methyl methacrylate (MMA) and 100 parts by weight of toluene as an organic solvent are mixed to obtain a monomer mixture liquid.
[0114] After bubbling the obtained monomer mixture with nitrogen for 20 minutes to remove dissolved oxygen, the inside of the separable flask was replaced with nitrogen, and the oil tank was heated to 130°C while stirring. A solution obtained by diluting 2,2'-azobis[2-(2-imidazolin-2-yl)propane] with terpineol as a polymerization initiator was added. In addition, the terpineol solution containing the polymerization initiator was added several times during the polymerization, and a total of 1.5 parts by weight of the polymerization initiator was added with respect to 100 parts by weight of the monomer.

[0118] (Example 3)
[0119] In a 2L separable flask equipped with a stirrer, a cooler, a thermometer, a hot water bath, and a nitrogen inlet, 100 parts by weight of methyl methacrylate (MMA) and 200 parts by weight of terpineol as an organic solvent were mixed to obtain Monomer mixture.
[0120] After bubbling the obtained monomer mixture with nitrogen for 20 minutes to remove dissolved oxygen, the inside of the separable flask was replaced with nitrogen, and the oil tank was heated to 130°C while stirring. A solution obtained by diluting 2,2'-azobis[2-(2-imidazolin-2-yl)propane] with terpineol as a polymerization initiator was added. In addition, the terpineol solution containing the polymerization initiator was added several times during the polymerization, and a total of 10 parts by weight of the polymerization initiator was added with respect to 100 parts by weight of the monomer.
