20110178251 | Water Absorbing Material - The present invention relates to a water-absorbing material obtainable by a process comprising the steps of A) treating a particulate, non-surface-crosslinked, water-absorbing polymer with a mixture comprising an aqueous solvent and at least one salt of a transition metal and B) irradiating the polymer treated according to A) with UV radiation, to a process for its production and to articles comprising the water-absorbing material. | 07-21-2011 |
20120016079 | PROCESS FOR PREPARING SOLUTIONS OF RADIATION-SENSITIVE, FREE-RADICALLY POLYMERIZABLE ORGANIC COMPOUNDS - A description is given of a process for preparing solutions of radiation-sensitive, free-radically polymerizable organic compounds, where a first starting compound, which has an acid halide group, and a second starting compound, which has an alcoholic hydroxyl group, are esterified with one another in a solvent or in a solvent mixture. The solvent comprises one or more ketones having a boiling point of below 150° C. under atmospheric pressure (1 bar), or the solvent mixture is composed to an extent of at least 50% by weight of said ketones. One of the two starting compounds has at least one radiation-sensitive group and the other of the two starting compounds has at least one ethylenically unsaturated, free-radically polymerizable group. A description is also given of corresponding solutions of radiation-sensitive, free-radically polymerizable organic compounds and of their use for preparing radiation-crosslinkable, free-radically copolymerized copolymers, more particularly for hotmelt pressure-sensitive adhesives or aqueous polymer dispersions. | 01-19-2012 |
20120067715 | METHOD FOR PURIFYING CARBOXYLIC ACIDS CONTAINING HALOGEN COMPOUNDS - In a process for purifying carboxylic acids comprising halogen compounds, the carboxylic acid is distilled in the presence of a nonvolatile auxiliary base, the halide of which is liquid at the boiling temperature of the carboxylic acid. The auxiliary base binds the hydrogen halide which is present in the carboxylic acid and/or has been eliminated from halogen compounds as a result of thermal action and lowers the vapor pressure thereof in this way, such that the hydrogen halide is held in the distillation bottoms and is not transferred into the distillate. Since the halide of the auxiliary base is liquid, the formation of solid deposits in the distillation apparatus is prevented. The carboxylic acid optionally also comprises at least one low boiler. | 03-22-2012 |
