摘要： PROBLEM TO BE SOLVED: To manufacture using a raw material that can be easily obtained by using gaseous trifluoromethyl polyfluoroalkyl ether in gas form at a room temperature as a gaseous fire extinguishing chemical substitute for a gaseous carbon halide fire extinguishing chemical, the use of which is regulated because it depletes the ozone layer. SOLUTION: To make an alternative gaseous fire extinguishing chemical having the capability comparable to the fire extinguishing capability of carbon halides under regulations, a gas whose main component is trifluoromethyl polyfluoroalkyl ether expressed by the formula CF3O-R is used. In the formula, R is CHFCF3 or CF=CF2. As a fire extinguishing chemical made from the trifluoromethyl polyfluoroalkyl ether has hydrogen atoms or a double bond on an α-carbon in the molecule, the atmospheric life is far shorter than perfluoro compounds and as it does not contain bromine atoms that may cause the depletion of the ozone layer, it is suitable as a substitute fire extinguishing chemical substituting for regulated carbon halides.

摘要： PROBLEM TO BE SOLVED: To provide a separating and determining method for fluorine- containing carboxylic acid with ion-exclusion chromatography. SOLUTION: This separating and determining method for fluorine-containing carboxylic acid comprises a mixing process mixing specimen liquid containing fluorine-containing carboxylic acid with elutant comprising aqueous acid, and a column separating process for separating the fluorine-containing carboxylic acid in the specimen by passing a resultant mixed liquid through a separation column filled with a hydrogen type weakly acidic cationic exchange body. Ion-exclusion chromatography for the separating and determining method for fluorine-containing carboxylic acid has a characteristic that the electric conductivity of discharged liquid flowing out of the separation column is measured, and the fluorine-containing carboxylic acid separated based on the ion chromatography is quantified.

摘要： PURPOSE:To obtain a negative type resist material having high resolution and excellent drying etching resistance by using a polymer into which a specific structural unit is incorporated. CONSTITUTION:The polymer into which the structural unit expressed by the formula (Z is an arylene group) is incorporated is used as the resist material. Such polymer has a high sensitivity to high energy rays such as electron rays and gamma rays and is crosslinked when irradiated with such rays. The polymer is thus used as a negative type resist. Since the polymer hardly swells for its structure, the polymer is hardly affected by mol.wt. and mol.wt. distribution; the higher mol.wts. are more preferable in terms of the higher sensitivity to the electron rays. The excellent negative type resist having the high resolution is obtd. by using such polymer and is used for production of, for example, integrated circuits, magnetic bubbles, printing plates, shadow masks, etc.
