YieldReaction ConditionsOperation in experiment
In diethyl ether; Synthesis Example 2 for Monomer (Synthesis of 2-ethyl-2-adamantyl methacrylate) A solution was prepared by adding 50 parts of diethyl ether to 31.1 parts of 2-adamantanone. While keeping the temperature of the solution at or under 10C, 200 ml of a diethyl ether solution containing ethyl lithium at a concentration of 1.14 mole/liter was added dropwise thereto. The solution was stirred at 0C for 2 hours, and then, while keeping the temperature of the solution at or under 10C, 26.2 parts of methacryloyl chloride (1.2 mole based on <strong>[702-98-7]2-methyl-2-adamantanol</strong>) was added dropwise. After the completion of addition, the solution was stirred at room temperature for 12 hours. Then precipitated inorganic salts were removed by filtration. The organic layer was washed with 5% aqueous sodium hydrogen carbonate solution and then washed twice with water. The organic layer was concentrated and distilled under reduced pressure to give 2-ethyl-2-adamantyl methacrylate represented by the following formula:

To the solution was added azobisisobutyronitrile as an initiator in a ratio of 2 mol % based on all monomer molar amount, and the mixture was heated at 80 C. for about 8 hours. Then, the reaction solution was poured into large amount of heptane to cause precipitation, and this operation was repeated three times for purification. As a result, copolymer having a weight-average molecular weight of about 9,200 was obtained. This is called resin A1.

The monomer M1, monomer M2 and monomer M3 were dissolved in 2 times amount of methyl isobutyl ketone as much as the amount of all monomers to be used (monomer molar ratio; monomer M1: monomer M2: monomer M3=5:2.5:2.5). To the solution, 2,2'-azobisisobutyronitrile was added as an initiator in a ratio of 2 mol % based on all monomer molar amount, and the resultant mixture was heated at 80 C. for about 8 hours. The reaction solution was poured into large amount of heptane to cause precipitation. The precipitate was isolated and washed twice with large amount of heptane for purification. As a result, copolymer having a weight-average molecular weight of about 9,200 was obtained. This copolymer had the following structural units. This is called as resin R1.

YieldReaction ConditionsOperation in experiment
With 2,2'-azobis(isobutyronitrile); 2-hydroxyethanethiol; In propylene glycol methyl ether acetate; at 80℃; for 6h; Synthesis Example 2-1; Synthesis of Polymer 1; A flask purged with nitrogen was charged with 168.6 g of 2-ethyladamantan-2-yl methacrylate, 85.5 g of <strong>[115372-36-6]3-hydroxy-1-adamantyl methacrylate</strong>, 172.1 g of 2-oxotetrahydrofuran-3-yl methacrylate, and 510 g of propylene glycol methyl ether acetate (PMA) to form a monomer solution. An initiator solution was prepared by adding 14.86 g of 2,2'-azobisisobutyronitrile and 2.6 g of 2-mercaptoethanol to 127 g of PMA. Another flask purged with nitrogen was charged with 292 g of PMA, which was heated at 80C while stirring. Thereafter, the monomer solution and the initiator solution were simultaneously added dropwise over 4 hours. After the completion of dropwise addition, the polymerization solution was stirred for a further 2 hours while maintaining the temperature of 80C, and thereafter, cooled down to room temperature. With vigorous stirring, the polymerization solution was added dropwise to 12 kg of methanol, whereupon a copolymer precipitated. The copolymer was collected by filtration, washed twice with 3 kg of methanol, and vacuum dried at 50C for 20 hours, obtaining 384 g of the copolymer in white powder form. The copolymer was analyzed by 13C-NMR, finding a copolymerization compositional ratio of 33/18/49 mol% in the described order of monomers. It was also analyzed by GPC, finding a weight average molecular weight (Mw) of 6,000 versus polystyrene standards.
