Abstract
Official abstract text for this publication.
A vinylpyridine resin that is hardly pulverized and thermally decomposed such that the degradation of the catalytic activity is suppressed while having a pore volume and a specific surface area to maintain a sufficient catalytic activity, and also a method of manufacturing the vinylpyridine resin are provided. The resin represents: a volume ratio of the pores having a diameter of 3 through 5 nm to all the pores of not less than 4% and not more than 60%; a total pore volume of not less than 0.15 cc/g and not more than 0.35 cc/g; and a specific surface area of not less than 20 m 2 /g and not more than 100 m 2 /g. The resin can be manufactured by using a poor solvent and not less than 50 wt % and not more than 90 wt % of a good solvent as porous agent.
First claim
Opening claim text (preview).
What is claimed is: 1. A vinylpyridine resin to be used for catalyst carriers, exhibiting characteristics of: a volume ratio of pores having a diameter of 3 through 5 nm to all the pores of not less than 4% and not more than 60%; a total pore volume of not less than 0.15 cc/g and not more than 0.35 cc/g; and a specific surface area of not less than 20 m 2 /g and not more than 100 m 2 /g. 2. A vinylpyridine resin to be used for catalyst carriers according to claim 1 , wherein the vinylpyridine resin is a copolymer of vinylpyridine and divinylbenzene.
