摘要:A hydroxyl-containing monomer of formula (1) is provided wherein R 1 is H, F, methyl or trifluoromethyl, R 2 and R 3 are monovalent C 1 -C 15 hydrocarbon groups, or R 2 and R 3 may form an aliphatic ring. The monomers are useful for the synthesis of polymers which have high transparency to radiation of up to 500 nm and the effect of controlling acid diffusion so that the polymers may be used as a base resin to formulate radiation-sensitive resist compositions having a high resolution.

摘要:The present invention relates to a method for synthesizing a radiopharmaceutical using a cartridge, which makes it possible to carry out several steps of reaction required for synthesizing a radiopharmaceutical in the cartridge filled with a polymer. A method for synthesizing a radiopharmaceutical according to the present invention enables each step's reaction to be carried out with the solution confined in the cartridge so as not to flow out, thus being simplified compared to the conventional methods for synthesizing radiopharmaceuticals, and expediting the synthesis thereof.
