<P>PROBLEM TO BE SOLVED: To provide a vinylpyridine resin, which is hard to powder and thermally decompose, contains many pores of a small size such that deterioration of carbonylation catalyst activity of methanol by thermal decomposition is suppressed, and has a pore capacity and a specific surface area which can provide sufficient catalyst activity. <P>SOLUTION: The vinylpyridine resin has a capacity ratio of pores having pore a diameter of 3-5 nm to all pores of 4% or more and 60% or less, an overall pore capacity of 0.15 cc/g or more and 0.35 cc/g or less, and a specific surface area of 20 m<SP POS="POST">2</SP>/g or more and 100 m<SP POS="POST">2</SP>/g or less. The method of producing the vinylpyridine resin includes using a poor solvent and a good solvent in combination as porous agents, the amount of the good solvent being 50 wt.% or more and less than 90 wt.% relative to the total weight of the porous agents. <P>COPYRIGHT: (C)2012,JPO&INPIT |
