Abstract
A composite separating agent which comprises a hydrophilic polymer separating agent showing a degree of swelling in water of 10 to 100 ml/g-dry and having a giant network structure incorporated within pores of an organic polymer substrate showing a degree of swelling in water of 20 ml/g-dry or below and a degree of crosslinking of 4% to 100% by mol and having a porous structure as well as a process for producing the same are disclosed. When packed within a column, this composite separating agent having a high mechanical strength is hardly compacted and exhibits an excellent separation performance. Thus it is highly useful in chromatographic separation of biopolymers including proteins.
