Abstract
A porous polymeric medium having a low affinity for amide group-containing materials is provided comprising a porous polymeric substrate and a surface-modifying polymeric material having a low affinity for amide group-containing materials formed in situ at and covalently bonded to the surface of the porous polymeric substrate, the surface-modifying polymeric material being formed from a monofunctional monomer having at least one hydroxyl group.

A porous polymeric medium having a low affinity for amide-group containing materials comprising:
- a porous polymeric substrate;
- and
- a surface-modifying polymeric material having a low affinity for amide group-containing materials formed in situ at and covalently bonded directly to the surface of said porous polymeric substrate, said surface-modifying polymeric material being derived from an unsaturated monofunctional misnomer having at least one hydroxyl group.
A porous polymeric medium having a low affinity for amide group-containing materials comprising:
- a porous polymeric substrate;
- and
- a hydroxyl-containing surface-modifying polymeric material having a low affinity for amide group-containing materials formed in situ at and covalently bonded directly to the surface of said porous polymeric substrate, said surface-modifying polymeric material being derived from an unsaturated monofunctional monomer having at least one hydroxyl group or group capable of forming same.
