    摘要: The invention refers to salts of at least one imidazole of the general formula (I), in which R1, R2, R3 and R4 are the same or different and denote hydrogen, an alkyl residue having 1 to 20, preferably 1 to 10, more preferably 1 to 4 carbon atoms, or a substituted or unsubstituted aryl or arylalykl residue having 6 to 10 carbon atoms, and at least one aliphatic or aromatic mono- or dicarboxylic acid. The molar ratio of carboxylic acid to imidazole, based on the functionality of the acid, is 1:1.1 to 1:6. The invention also relates to a method for manufacturing the imidazole salts, to their use, and to epoxy resin compositions containing said salts.

    摘要: The subject matter of the invention is an innovative method for the separation of polymer systems regarding their molecular weight, chemical structure, chain architecture, and colloidal additives. Such separations are currently accomplished by selective precipitation from solution, by a fractionated crystallization also from solution, and by means of gel chromatographic methods.The invention pertains to a separation of polymer systems by means of permeation through polymer films—semi-crystalline, cross-linked, amorphous—with thicknesses in a nanometer scale. The restriction to thicknesses in a nanometer scale is essential for a high throughput of polymers. Of particular significance is the selectivity towards colloidal additives with a structure that is not in chain form.
