    摘要: A method and system for norming and/or standardizing product features, wherein the product features are defined by characteristic elements. A pool (e.g. a data base or a product catalog) comprising product features and characteristic elements is accessed bin a defined and controlled way to ensure that all data entries are based on a norm or a standard. This improves the interchangeability of in particular technical data within a company and also enables the exchangeability of in particular technical data between companies (CRM). Another aspect of the invention is a method and a system for searching a product, wherein the product features are defined by standardized elements or components.

    摘要: Process for preparing fine-particle, water-insoluble polymers of aziridines by polymerizing aziridines, preferably ethylenimine, in the presence of crosslinkers which contain at least two functional groups, and in at least one ether, and also modified, water-insoluble polymers of aziridines which can be obtained by reacting fine-particle, water-insoluble, crosslinked polymers of aziridines, in aqueous medium, with carbon disulfide or formaldehyde and a nucleophilic agent from the group consisting of alkali metal cyanides, primary amines, secondary amines, alkali metal sulfites and alkali metal phosphites, and use of the modified and non-modified fine-particle, water-insoluble polymers for immobilizing active compounds, as absorbents for aldehydes, ketones and acids, and also for removing heavy metal ions from wastewaters.

    摘要: Cyclic N,N'-dimethylureas I ##STR1## where A is a 1,2- or 1,3-alkylene group of 2 to 10 carbon atoms, are prepared by reacting the corresponding non-methylated cyclic urea with formaldehyde and excess formic acid and then removing the formic acid still present in the reaction mixture, by a process in which the formic acid is subjected to a thermal decomposition reaction by means of a catalyst system consisting of a tertiary amine and a copper salt.
