| 摘要 |
The invention relates to adducts, which can be obtained by means of a method involving the step of reacting a renewable raw material (particularly raw materials and recyclings, which contain carbohydrates and which are from the areas of agriculture, forestry, fish farming, paper industry and foodstuffs industry) with a polyamine selected from the group consisting of polyalkylene polyamines and polyalkylene imines. The adducts can be chemically or thermally cross-linked by means of additional method steps. These adducts are suited for use as adsorber materials, particularly as ion exchangers for the exchange of heavy metals, for decontaminating gasses, soils and waste waters. |
