摘要： A nuclear halogenated aromatic compound possessing cyano groups is produced by a method using as a raw material an aromatic compound which possesses cyano groups and assumes a solid state at room temperature and subjecting the raw material to a procedure comprising a step of melting and transporting the compound by a means transport-melting, a step of vaporizing the compound, a step of mixing the compound with a halogen gas, and a step of causing the vapor of the compound to react with the halogen gas in vapor phase in the presence of a catalyst sequentially in the order mentioned, which comprises maintaining a content of a self-condensate of the aromatic compound possessing cyano groups which arise during the melting of the aromatic compound possessing cyano groups in a gas of the compound which reacts with the halogen gas to a level of not more than 2.5 mol % based on the compound. The catalyst used in the method is activated carbon such that the average pore radius thereof determined by the nitrogen adsorption method is not less than 12.2 .ANG. and the cumulative pore volume of the portion of the activated carbon having pore radiuses in the range of 5-100 .ANG. determined by the steam adsorption method is not less than 0.45 g/cc.

摘要： A carboxylic acid polymer containing a carboxylic group and having at least one kind of bond selected from the group consisting of an amino bond, an ether bond, and a thioether bond in a side chain is prepared by polymerizing a monomer component containing a carboxylic acid monomer represented by General Formula (3): ##STR1## where Y.sub.4 is a hydrogen atom, an allyl group, or a --(CHR.sub.4).sub.c --W.sub.2 --(CHR.sub.5).sub.d --COOR.sub.6 group, each of R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6, independent of the others, is either a hydrogen atom or an alkyl group of a carbon number from 1 to 6, each of W.sub.1 and W.sub.2, independent of the other, is either an --NH-- group, an --S-- group, or an --O-- group, and each of a, b, c, and d, independent of the others, is an integer from 0 to 6. The carboxylic acid polymer has a superior metal-scavenging ability (chelating ability) and can be suitably used, for example, as a chelating agent.
