CHROMATOGRAPHY MATERIALS, A PROCESS FOR THEIR PREPARATION AND USE OF THE MATERIALS

摘要

Products comprising a base matrix consisting of a copolymer of low molecular weight vinyl monomers and a polyhydroxy polymer, for example dextran, carrying vinylic groups on the polymer chain, which base matrix is modified with ion exchange groups. The products, which can be prepared by direct bonding of ion exchange groups, are useful in chromatographic separation processes based on ion exchange principles.
