Abstract
A monolith separation medium comprising a skeletal phase and continuous pores forming a three-dimensional network structure, which has a functional group enabling the introduction of a new functional group on the surface of the skeletal phase. The skeletal phase has an average diameter of a submicron to micrometer size and is in a co-continuous structure of the non-particle-aggregation type. It is composed of an addition polymer of 1,3-bis(N,N′-diglycidylaminomethyl)cyclohexane as an epoxy compound with a bifunctional or higher amine compound, is rich in organic matters and is free from any aromatic-origin carbon atom. Thus, it is an organic polymer monolith separation medium of the non-particle-aggregation type.
