Route of Synthesis (ROS)
| Conditions | Yield |
| With dimethyl 2,2′-azobis(isobutyrate) In butanone at 80℃; for 10h; Experimental Procedure Synthesis Example 14 A monomer solution was prepared by dissolving 55.00 g of 5-oxo-4-oxatricyclo[4.2.1.03,7]nonan-2-yl methacrylate, 11.70 g of 3-hydroxyadamantan-1-yl methacrylate, and 33.31 g of 1-ethylcyclopentyl acrylate in 200 g of 2-butanone, and further adding 4.56 g of dimethylazobisbutyrate. A 1,000 ml three-necked flask containing 100 g of 2-butanone was purged with nitrogen for 30 minutes. Then, while the contents were heated to 80 C with stirring, the above monomer solution was added dropwise over four hours using a dropping funnel. Polymerization was initiated at the start of dropping and continued for six hours. After the polymerization, the polymer solution was cooled with water to 30 C or lower and poured into 2,000 g of methanol. White precipitate produced was collected by filtration. The resulting white powder was washed twice with 400 g of methanol in the form of a slurry, filtered, and dried under reduced pressure for 17 hours at 50 C to obtain a white resin powder. The resin was found to have Mw and Mw/Mn of 8,500 and 1.75, respectively. The result of 13C-NMR analysis confirmed that the resin was a copolymer of 5-oxo-4-oxatricyclo[4.2.1.03,7]nonan-2-yl methacrylate, 3-hydroxyadamantan-1-yl methacrylate, and 1-ethylcyclopentyl acrylate at a copolymerization molar ratio of 53.7:11.1:35.2. This resin is referred to as a “resin (B-10)”. |
