Abstract
The invention relates to new bead-shaped crosslinked macroporous copolymers containing epoxide groups and basic amino groups, which are obtainable by reacting polymerizable glycidyl compounds, before or during free radical bead polymerization, which is carried out in the presence of agents which impart porosity and, if appropriate, with the addition of polyvinyl compounds which can be polymerized by free radical polymerization, with amines which are capable of reacting with at least two epoxide groups, a process for their preparation and their use, for example, for binding biologically active substances, for the preparation of strongly basic anion exchangers and hydrophilic chromatography resins for biomaterials.
