Amino-containing polymeric material with rigid and contorted divinyl crosslinker

Abstract

Amino-containing polymeric materials and methods of making these materials are provided. More specifically, the amino-containing polymeric materials are prepared by treating a precursor polymeric material with an amine compound. The precursor polymeric materials are formed from a polymerizable composition that contains a rigid and contorted divinyl crosslinker. The amino-containing polymeric materials can be used as anion exchange resins.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application 61 / 823,161, filed May 14, 2013, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The amino group-containing polymer material is prepared using free radical polymerizable spirobisindene monomer as a crosslinking agent. The resulting amino group-containing polymeric material and methods of preparing the amino group-containing polymeric material are described. Background technique [0004] There is a need for ion exchange resins used in high pressure chromatography columns that are able to withstand the higher pressures and / or higher temperatures commonly encountered. Higher pressures often confer greater separation power. Such ion exchange resins are typically crosslinked to provide resilience to deformation or fracture under high pressure and / or high temperature conditions. For example, many ...
