    摘要： This invention provides a drilling fluid containing additives composed of copolymers which are obtainable by an industrially favorable process and superior in heat-resisting property. Even though the additives are used in a relatively small amount, such an amount sufficiently prevents changes in the properties of drilling fluid due to various kinds of hard water components being contained in underground water or cement as well as due to sea water, and the additives are able to display the properties of drilling fluid constantly regardless of presence or absence of salts.Drilling fluid additives of the present invention are composed of a water-soluble copolymer (A) having an average molecular weight of 1,000-50,000. The water soluble copolymer (A) is composed of 40-99.5 mole percent of an unsaturated carboxylic acid monomer (I), as shown in the following general formula (I), and 0.5-60 mole percent of an unsaturated (meth)allylether monomer (II), as shown in the general formula (II). ##STR1## In the formula (I), each of A.sup.1 and A.sup.2 independently represents hydrogen, methyl, or --COOX.sup.2 and A.sup.1 and A.sup.2 are not COOX.sup.2 at the same time. A.sup.3 represents hydrogen, methyl, or --CH.sub.2 COOX.sup.3 and, in a case that A.sup.3 is --CH.sub.2 COOX.sup.3, each of A.sup.1 and A.sup.2 independently represents hydrogen or methyl. Each of X.sup.1, X.sup.2, and X.sup.3 independently or at the same time represents hydrogen, monovalent metal, divalent metal, ammonium, or organic amine.In the formula (II), R.sup.1 represents hydrogen or methyl, and Z represents hydroxyl; a sulfonic acid group or its monovalent metal salt, divalent metal salt, ammonium salt, and organic amine salt; a phosphoric (or phosphorous) acid group or its monovalent metal salt, divalent metal salt, ammonium salt, and organic amine salt.

    摘要： A catalyst composition including component A and component B, the component A being a carrier, preferably having a honeycomb structure, and being a single-component oxide or a multi-component composite oxide of at least one metal of titanium, silicon and zirconium, and the component B being a catalyst component deposited on the carrier of component A and being at least one member selected from the group of noble metals and other specifically limited metals and their oxides, is very effective for decomposing and removing poisonous organic chlorine compounds, such as dioxin and the like, or poisonous organic chlorine compound-forming substances contained in an exhaust gas exhausted from an incinerator of an incineration plant provided with the incinerator and a dust collector. In addition, and the generation of the poisonous organic chlorine compound from the incineration plant can be prevented.
