Aqueous romp-based monolith materials and methods for making

Abstract

A water soluble ROMP catalyst, which has high catalytic efficiency for ring opening metathesis is use in the preparation of polymeric blends for use in monolithic columns. In one embodiments a method for making a polymeric blend is discolosed comprising reaction of a water-soluble ROMP catalyst with a norbornene-substituted cycloolefin polymer or a polynorbornene polymer precursor, and wherein the contacting occurs in an aqueous or polar solvent in the presence of a solid support. In another embodiment a monolithic bed is disclosed comprising the water-soluble ROMP catalyst immobilized on a surface of a solid support. Also disclosed is a monolithic bed comprising: a polymer blend, the polymer blend produced from contacting a water soluble ROMP catalyst with a norbornene-substituted cycloolefin polymer or a polynorbornene polymer precursor; and wherein the contacting occurs in an aqueous or polar solvent in the presence of a solid support.
