Embodiment 1

[0084] Embodiment 1 is a sulfonyl-containing polymer material comprising the reaction product of a reaction mixture comprising a) a precursor polymer material and b) a sulfonyl-containing compound. The precursor material includes the polymerization product of a polymerizable composition comprising i) a monomer mixture and ii) a free radical initiator. The monomer mixture comprises 1) a first monomer of formula (I)

[0085]

[0086] and 2) a second monomer which is styrene, styrene substituted with one or more alkyl groups, or a combination thereof, wherein the first monomer of formula (I) is based on the second monomer present in an amount of up to 25 mole % based on the number of moles. In monomers of formula (I), each R 1 is hydrogen, halogen, alkyl, aryl, alkaryl or aralkyl, where at least one R 1 is hydrogen. each R 2 independently hydrogen, alkyl, aryl, alkaryl, aralkyl, with R attached to the same carbon atom 3 combined to form cycloalkyl, or with R attached to ...

Embodiment 2

[0087] Embodiment 2 is the sulfonyl-containing polymer material of embodiment 1, wherein each R in the first monomer 1 is hydrogen or halogen.

Embodiment 3

[0088] Embodiment 3 is the sulfonyl-containing polymer material of embodiment 1 or 2, wherein each R in the first monomer 2 and each R 3 is an alkyl group.

Abstract

Sulfonyl-containing polymeric materials are prepared by treating a precursor polymeric material with a sulfonyl-containing compound. The precursor polymeric materials are formed from a polymerizable composition that contains a crosslinker that is a free-radically polymerizable spirobisindane monomer. The sulfonyl-containing polymeric material can be used as an ion exchange resin.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application 61 / 823,155, filed May 14, 2013, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The polymeric material is prepared using free-radically polymerizable spirobisindene monomers as the crosslinker is functionalized to provide sulfonyl-containing groups. A sulfonyl-containing polymer material that can be used as an ion exchange resin and a method of preparing the sulfonyl-containing polymer material are described. Background technique [0004] Ion exchange resins for high pressure chromatography columns are expected to be able to withstand the relatively high pressures and / or high temperatures commonly encountered. Higher pressure generally confers higher separation power. Such ion exchange resins are typically cross-linked to provide resilience to deformation or fracture under high pressure and / ...
